On this page, you will find all important information, instructions, and guidance related to our older and discontinued hörbert models. If you own an earlier hörbert, you can conveniently find the appropriate documentation, usage tips, as well as information on maintenance and possible spare parts here. We want to ensure that your hörbert – regardless of its year of manufacture – continues to accompany you reliably.
The hörbert 2021 is the model we manufactured and sold from October 2021 to March 2026. It can be identified by the fact that it has neither a mechanical toggle switch nor an LED indicator (only present on the latest hörbert 3.0) between the handle and the volume control. The device is available in a version with 11 buttons or 3 buttons.
In the hörbert Model 2011 (with toggle switch) you can use your own SDHC cards between 4 and 32GB. NO SDXC cards.
It should preferably be a Class4 or Class6 card.
We ask for your understanding that we cannot give a 100% guarantee for the use of third-party cards in our product that they will function perfectly with hörbert.
For example, we don’t know the power consumption of other cards. With Class10 cards this can be considerably higher than with our Class4 cards. In this case hörbert would not achieve its average playing time of approx. 50 hours – from memory card and at medium volume.
Before you can get started, a third-party SD card must first be formatted in FAT32 format.
Attention: This will delete all data on the card and reset it. So you should back up the contents to your hard drive beforehand if there is already content on a third-party card.
You can format a memory card for hörbert 2011 with the hörbert software
(Version 1.4.14 -> Step 1 -> Memory card tools -> Format card;
Version from 2.1.x -> Read in card, then in the menu above go to Extras -> Format memory card)
or with your computer’s built-in tools via the disk utility.
Please try the following after starting the hörbert software and inserting the SD card. In the software menu at the top, go to Extras -> Select destination manually. The card should then be selectable there.
If this is not possible, our development department has taken precautions:
You can simply select a file folder on your hard drive – and not your memory card. After that, the hörbert software works on the file folder as if it *were* a memory card. And if your memory card is usable with the card reader under your operating system and mounted correctly, you can simply copy the contents of this folder to the memory card afterwards. This feature is intended for when the memory card’s mount directory still doesn’t work for some reason, and when alternatives like “Sox” also fail.
You want all this for your own hörbert too? No problem! Please contact our service team in order to get an offer for an Upgrade.
Visual differences:
The new hörbert comes with a slightly different appearance and a brand new electronic interior.
The toggle switch for switching on/off no longer exists. Instead, the volume control can be pressed for electronic on/off.
The new hoerbert’s front panel has a small opening at the right bottom, behind which the microphone is hidden.
hörbert now has even less plastic. The coloured buttons on the front now also consist of wood!
New features:
Proven and still available:
Due to the very high power consumption of these cards, the Bluetooth module may generate noise in the standard playback mode.
This does not happen with our supplied cards. We therefore recommend the use of the original hörbert memory card, so your hörbert will run longer.
A Transcend card tested by us (16 GB Class 10) had a much higher power consumption than our original cards.
This is of course bad for the runtime.
If you don’t want to do without your memory card, please contact our support team (service@winzki.de), because we can also upgrade your hörbert board for a small service fee if you wish, so that even such power-hungry memory cards can be operated almost without noise.
Note: Unfortunately, we cannot make any valid functional statements for third-party cards, as the manufacturing methods and what is installed inside are constantly changing. We purchase our own memory cards directly from the manufacturer according to our specifications.
IMPORTANT: please leave hörbert switched off and DO NOT switch it on again. Now the inside LED display of the Bluetooth module flashes twice per second and a beep sounds to indicate that hörbert is now in Bluetooth speaker mode.
You now have one minute to find hörbert in the list of Bluetooth devices on your phone and pair it with your phone.
You can start a playlist on your phone to play it via hörbert.
The first pairing of headphones with hörbert 2011 with a separate built-in bluetooth-module can take a minute, especially when there are many other Bluetooth devices nearby.
The headphone mode only searches for hörbert headphones in the first 60 seconds after switching hörbert on. In the headphone mode, the hörberts loudspeaker switches off as soon as the sound is heard in the headphones. If this does not work the first time, it will work the second (or third) time.
Please proceed as follows to find the solution:
If no: please charge the headphones fully first. If they still do not work, contact the dealer where you bought the headphones. There may be a defect in the headphones and the headphones must be replaced.
If so: go to steps 2 to 6:
Please do not activate any switches on the “Mouse Piano” of the Bluetooth module unless hörbert is switched off. If switch no. 6 (Pairing) is deactivated, e.g. when hörbert is switched on, under certain conditions all pairings stored by hörbert will be deleted. (See point 3.2.4.2 of our operating instructions for the Bluetooth module).
It is possible to change the name of paired devices in your Bluetooth transmitter.
You can find the necessary tips for this under the links below, depending on which device you use:

The strength of the electromagnetic radiation depends on the transmitting power of the devices.
The power class of the Hörbert Bluetooth module is class 2, i.e. our Bluetooth connections are all class 2 with a maximum transmission power of 2.5 mW (+4 dBm). The hörbert Bluetooth module thus complies with the recommended SAR maximum values in any case due to the very low transmission power.
That depends on the environment, whether there are obstacles, such as walls… in the way. However, the range can usually be about 15 m.
In hörbert mode you simply listen to the content with your hörbert — as usual. Just switch on your hörbert and it starts playing.
Even in this standard mode your hörbert 2011 will consume a little more power than a hoerbert 2011 without bluetooth-module, and it will therefore not reach its 50-hour runtime.
This is because the sound has to be looped through the Bluetooth module, which also needs a little power.
This slight buzzing, which is usually only heard in silent moments and only in piano mode, is due to the fact that the sound has to be “looped through” the Bluetooth module.
Noise can be minimized if all cables leading to the Bluetooth module are first twisted together as shown in the installation video and instructions.
Note: The buzzing sound may be amplified when using memory cards other than our original ones, as some cards draw more current than others.
hörbert comes ready to play.
Depending on your selection, a preloaded memory card is included with German, international, or Swiss German audio content for children. If you choose an accessible hörbert, you can also opt for a blank SD card or one with audio content for adults. The hörbert for seniors automatically includes the free memory card with content for adults.
We provide over two hours of carefully selected songs and stories.
Additionally, we include 4 AA batteries so you can start using hörbert right away after unpacking.
You are also welcome to use 4 rechargeable AA batteries in hörbert’s battery clips.
Important Note:
If you purchase a hörbert with an optional USB port and battery charging function, we also include a preloaded free memory card of your choice.
However, to operate hörbert via a power outlet, you will need the following accessories:
– USB power adapter
– USB-C cable
If you also want to use hörbert on the go, you will additionally need:
– 4 x rechargeable AA batteries (1.2V HR6)
You can find everything about hörbert’s USB port **HERE**.
We’ll agree on a price with you, because it always depends on what is broken.
If something is wrong with your hoerbert, please send us a note along with photos (<1.9 MB in size) to service (at) hoerbert (dot) com
As long as the decorated part is not broken, we’ll replace only other parts and you’ll get your own hörbert back, of course.
You might want to replace the handle, the loudspeaker, the on/off switch and the volume knob yourself. That’s okay, if you have the know-how and the tools to perform such a repair. If you don’t, contact us, so you can send your hörbert in for a repair.
When batteries leak, you will find traces of battery chemistry on the electronics (circuit board). You must cleanly remove these traces in order to get your hörbert back in shape.
Important safety instructions
Take care of your safety and that of your surroundings in the following activities! Only work with safety glasses! Only work with protective gloves! Don't touch anything else with your gloves on! Work with an open window and sufficient fresh air supply! Do not work near flames or ignition sources! Keep chemicals and tools away from children! This manual does not apply to other devices! Leave the repair to us, if you don't think you can take a step! Risk of injury: splashes of alcohol or battery chemistry in the eyes may cause serious eye injury. In the event of an accident, consult a doctor immediately. Fires may occur when working with high-proof alcohol. Have extinguishing agent ready. Alcohol can dry out your skin, so wear gloves! And again: Keep children away from chemicals and tools!
There are two reasons for this: Either the contents of the memory card have got mixed up, or the remains of leaking batteries affect the electronics. (In this case: Problems with leaking batteries?)
Attention: This tip does not apply to hörberts with a Bluetooth module. Please do not jiggle the switch if your hörbert has a built-in Bluetooth module.
hörbert has a very stable on/off switch. The manufacturer of the switch inserts a little grease into the switch. If this accumulates in the wrong place, this effect may occur. But that’s no problem: Just turn the switch on and off at least 50 times really fast and really energetically, then the grease splashes and the problem is solved.
Background knowledge: In a lamp the fat would simply go up in smoke with a spark, but there is no such amount of energy in hörbert. Therefore you may have to help mechanically. You can switch back and forth really powerfully and quickly, the switch tolerates it: We have deliberately chosen an oversized switch that resists playing children.
Yes, since 12/2020 the hörbert software is also available for Linux (tested on Ubuntu >16.0.4) for download here:
The publishers of our supplied content offer even more beautiful music and stories – in some cases even free of charge.
You can find the sources here: hörbert’s preregistered contents
In addition there are many contents which you can buy as MP3 download or M4a download and which really belong to you. In Amazon and iTunes you can find them under the category “”Music downloads””. There is not only music, but also stories to download.
The included 4 GB memory card for the new hörbert Model 2021 can hold approximately 50 hours of audio content when using MP3 files.
Our free cards, which we include as a product supplement, are preloaded with over two hours of children’s songs and stories. You can add your own favorite songs and stories to our content at any time or replace the content.
More information on loading your own audio content onto the memory card.
If you have a “hörbert 2011,” the 4 GB memory card included in the delivery can hold 1,000 minutes (or 17 hours) of content.
In our experience, even with these 17 hours, it takes several weeks to months before a child wants something different.
Yes. The current hörbert model reads SD cards between 4GB and 512GB in size.
How to do all this exactly, you’ll find out here:
You can format your own memory card in FAT32 format with the built-in tools of your computer. If this format isn’t available in your disk utility programme for formatting the SD card, you can also select FAT, EXFAT or MSDOSFAT.
Alternative without computer:
Create 9 folders for the nine playlists in the main directory of your SD card and name them from 0 to 8. 0 = dark purple button, 1 = red button, 2 = dark blue button, 3 = light green button, 4 = yellow button, 5 = dove blue button, 6 = light blue button, 7 = orange button, 8 = dark green button.
This then looks like this:
Note: For a hörbert with only 3 playlist buttons, you only create three folders (1 = red, 6 = light blue, 8 = dark green)
You can now copy/drag your own audio files into the respective folders using copy&paste or drag&drop. Possible formats: mp3, wav
The playback order is solved by appropriate numbering of the track names, e.g.
1_Track name
2_Track name
3_Track name
etc.
or with spaces between number and track name:
1 Track name
2 Track name
3 Track name
etc.
Finished! Now you can properly eject the card, disconnect it from your computer and test it in hörbert.
If the Butterfly firmware is already installed on your hörbert, you can also transfer new audio files via Browser Set Mode (via tablet, smartphone or computer). hörbert then handles this via its WLAN. It will take somewhat longer to transfer lots of data than via the SD card reader on your computer.
In Browser Set Mode, select one of the colourful playlist buttons, then select “Playlist content” and click on the blue “FILE” button to select and transfer new audio files.
You can then move the file to another position in the playlist using the icon with the three lines (see image below):
Note: If you’ve once edited or opened the playlist contents of your SD card in Browser Set Mode, hörbert creates a file called “playlist.m3u” in the playlist. This ensures the correct playback order. New files that you subsequently add to playlist folders 0 to 8 via your computer’s file directory will always be played at the end of the playlist in alphabetical order.
You can then change the playback order in Browser Set Mode by dragging the tracks to another position there.
You can find a detailed description in our instructions for hörbert with Butterfly firmware
No, don’t worry. He just is out of power. Simply replace the batteries by new or charged ones (in case they are rechargeable batteries), then hörbert will play again normally.
Each of the nine coloured buttons represents a list of songs or audio book chapters. By pressing the same button several times, you jump through that list track by track.
You find all details about hoerbert’s functions in our user manuals:
MANUALS
The metallic grey button is used for audible fast forward, the black button jumps back to the beginning of the current title. Pressing the black metallic button twice you will jump back one more title.
hörbert is made of natural materials, that’s why we can’t predict colors and texture of the wood, for example. Each hörbert is unique! Small discolorations or knot-holes leave their traces and are normal.
The answer is yes and no.
The standard hörbert is a portable device and has no mains connection. It runs on 4 x AA rechargeable batteries or batteries, which are available everywhere. Here, a power connection with a power supply is omitted so that hörbert is also suitable for the youngest and always mobile, and there is no danger from power connections or cables.
Since November 2024, however, there is also hörbert for seniors and hörbert accessible. In this area, it is often necessary that hörbert can also be operated stationary via mains power. Therefore, these models automatically come with USB connection and battery charging function in the standard version.
Even with hörbert for children, you have the option to optionally choose a USB connection and suitable rechargeable batteries when purchasing.
The USB_C connection is only usable with a hörbert model 2021 (without toggle switch). The Firmware Butterfly must also be installed on the hörbert.
You can learn more about the USB-C connection of hörbert in our BLOG ARTICLE ON THE USB CONNECTION
Does hörbert have a USB port?
Yes, but not for USB sticks. It is used for operation via a USB-C cable and a USB power adapter plugged into a socket. If rechargeable batteries are also inserted in the internal battery compartment, they will be charged simultaneously when hörbert is connected to the socket via a USB-C cable. A practical feature. MORE INFO ABOUT THE USB PORT
Where are the audio contents stored?
hörbert works with a memory card in SD card format.
You need an SDHC card reader on your computer to save your own content to this memory card and to make changes to it.
Alternative option without a computer and without an SD card reader
Since the end of November, the Butterfly firmware has been available for all hörbert devices from October 2021 onwards. This is the model with a rotary knob for turning on and off. With this firmware, all settings for hörbert can be configured via the Browser Set Mode, a user-friendly web interface, which also allows you to add individual audio files or web radio URLs.
Important note: For the new hörbert model 2021 with Butterfly firmware (release October 2024), you no longer need hörbert software to load the memory card. You can do this conveniently via the browser set mode or save your own files to the SD card using copy & paste via your computer’s file manager.
Find out more in this BLOG ARTICLE.
For the older hörbert model 2011 with toggle switch, you will need the hörbert software. There is also an upgrade option for your hörbert 2011 to the new version.
The software is included on the memory card of a new hörbert. As we cannot guarantee that this is the latest version of the hörbert software, we recommend downloading the latest version from this page:
System requirements:
PC or Mac (Intel), operating system: Windows 10 or higher, or Mac OS X version 10.14 or higher, Linux (tested on Ubuntu
>16.0.4) If you have an operating system older than those mentioned above, please contact our service team for support.
Screen resolution of at least 1024×768 pixels
At least 4 GB of free hard disk space
At least 2 GB of RAM
hörbert accepts files in the following common formats: mp3, wav – with the restriction that DRM (Digital Rights Management)-protected files won’t work. DRM content from (streaming) services like Audible or Deezer are copy-protected and can be played by hörbert.
However, the current hörbert model offers the possibility to simultaneously record the Bluetooth streams that hörbert is currently playing. This way you can get new audio content for free if you pair hörbert with your phone, then stream the Spotify, deezer, audible… playlist to hörbert and record it at the same time.
Furthermore, the new hörbert can serve as a radio for internet radio streams. You can also record this content simultaneously onto hörbert’s memory card whilst listening.

The wood, operating elements and electronics have been specifically selected and produced in a way to protect hoerbert and your children, when it gets a bit wild in the playroom. hörbert will go through interesting times and may even get some marks and scratches that can easily be corrected with a bit of sand paper. If hörbert should have an unfortunate fall and something gets broken, spare parts are available – because throwing hörbert away is out of the question. Of course, you can also send hörbert in for repair at any time, we will be happy to advise you.
Please always CONTACT US before sending your hoerbert in for repair.
hörbert is available in our online shop at https://www.hoerbert.com, as well as in selected customer shops, that you can also find on our homepage. No matter where you buy your hörbert, you can have it individually engraved. Just ask at your customer shop, we’ll engrave your hörbert for you while we produce it.
hörbert was designed to be operated by even small children (from the age of two years) themselves without the help of anybody. Only transferring content to hörbert and replacing batteries are tasks that are left to grown-ups. As hörbert already comes with lots of songs and audio books, you won’t have to sacrifice your first day with hörbert at your computer instead of giving it to your children.
We don’t recommend a minimum age for using hörbert. You may want to play lullabies to a baby, your two-year-old kid may be able to handle hörbert completely on his or her own. Maybe grandma or grandpa like to use hörbert as a pretty and simple music box, that’s also a task hörbert can handle.
Children use the colored buttons to select what to listen to next. Behind each of the nine colored buttons there can be several songs or chapters of a story. Skipping them works by pressing the same button several times. There’s one more grey button for an audible fast forward scan and one black one to jump right back to the beginning of the currently playing title. You can even jump further to the previous titles by pressing that ‘back’ button quickly in repeat. Finally, there is a rotary volume knob and a robust on/off switch.
Read all about hoerbert’s functions in our user manuals.
A CD with copy protection can normally be identified by the corresponding IFPI copy protection logo. It’s a black circle with a white triangle. You can find it here: https://de.wikipedia.org/wiki/Kopierschutz
A tip: It is recommended to read a CD first with a program like iTunes and import it to your computer. Then the transfer to hörbert’s memory card is even faster. ITunes also has a good converter that brings the tracks into the optimal format (m4a or better still mp3). This is similarly convenient under Windows with the Media Player, but you have to set the mp3 format there, because the hörbert software does not read files with the extension.wma. After importing into iTunes, you can drag and drop songs directly from the iTunes library to the corresponding playlist window in the hörbert software using the hörbert software.
A software is necessary to conveniently arrange the tracks in the playlists and in the correct order, because if you would simply copy MP3 files to a memory card, the player would still not know in which order it should play them from which button. Another advantage is that you can also use files in OGG, WAV or FLAC format and directly from audio CDs as source material, or other common formats, which is not possible with most MP3 players. Instead of referring to hörbert as an MP3, Ogg, WAV and FLAC Player, only the term “MP3 Player” can be used as category or generic name. Otherwise you would not find our hörbert in any shop, because there is not even a category for “Audio-Player”, but at most “MP3-Player”. The term “universal audio player for children” would of course be quite correct. But we have to meet the potential customers looking for a player and limit ourselves here to the term “MP3 player” as a generic term, although hörbert can do much more.
In the case of hörbert, the conversion of audio files later saves a lot of power during playback, so that you rarely have to change batteries, because decoding (always the same) MP3 files or other formats requires much more computing power and therefore power. You can leave that to the computer and listen to the decoded result. Another advantage is that you can also use files in OGG, WAV or FLAC format and directly from audio CDs as source material, or other common formats, which is not possible with a “normal” MP3 player. And here it comes: Since the hörbert software is necessary anyway to arrange the files in the right order in the right playlists, it can also perform all conversions for you at the same time, without you having to do anything for it. Instead of referring to MP3, Ogg, WAV and FLAC Player, only the term “MP3 Player” can be used as a category or generic name. Otherwise you would not find our hörbert in any shop, because there is not even a category for “Audio-Player”, but at most “MP3-Player”. The term “universal audio player for children” would of course be quite correct. But we have to meet the potential customers looking for a player and limit ourselves here to the term “MP3 player” as a generic term, although hörbert can do much more.
M4A files can be played by a hörbert with toggle switch when they have been transferred via the hörbert software. The fact that 0 minutes is displayed as playing time is a technical problem that occurs only once per file during upload, and then no longer:
Before transferring, the file is displayed with length 0, as the hörbert software cannot determine the length of m4a files before converting. The file is nevertheless transferred.
The next time you insert the memory card, the correct duration will be displayed in the playlist.
Tip: If it’s a very old .m4a file with copy protection (from around 2003-2014), it cannot be transferred to hörbert. For this, you need to download this file again without copy protection – Apple offers an “exchange” of these files: https://support.apple.com/en-us/HT201616
If hörbert remains mute after switching on, simply check the following in this order
If this is not successful, please try again hörbert cannot be switched on or turns on or off spontaneously?
Is the problem still there?
If you have a loose screw, you can tighten it yourself with feeling. This problem can be caused by differences in humidity and temperature when the wood”works” (expands or contracts slightly). Is the problem still there?
Could it be that you are using an extra fast Class10 card or faster? Some of these cards can have this effect. These cards perform internal clean-up or sorting functions at irregular intervals, but these disturb the data stream. That’s why the whole thing can’t be determined by a song or a playback time, the small microprocessor in the card sometimes does”its own thing”. Please test it, if possible, with a smaller/older/slower card (e.g. Class 4 or 6), then the problem should not occur. Tip: If possible use Class4 SDHC cards between 4 and 32GB. Our included cards are “Class 4” cards, recognisable by a 4 in circular “C”.
Yes. Small defects or scratches can even be removed with a fine sandpaper. The best way to repair major damage is to replace the affected parts so that stable and safe operation can be restored afterwards. For larger repairs you can send us your hörbert by prior arrangement. A complete housing replacement (i.e. replacement of the frame and the front using all your intact hörbert parts) can only be carried out in our workshop, as we can also carry out any necessary minor repairs – at the previously agreed flat-rate price, of course.
The hörbert 2011 is our model that we manufactured and sold from 2011 until October 2021. Thanks to its extremely minimalist electronics, this model offers an especially long playback time. You can recognize the hörbert 2011 by its mechanical toggle switch, which is located between the handle and the volume control knob.

More InformationPlease try the following after starting the hörbert software and inserting the SD card.
Go to the top menu in the software and select Tools -> Select target manually.
The card should then be selectable there.
If this is not possible, our development team has prepared a solution:
With manual selection, you can simply choose a folder on your hard drive – instead of the memory card. The hörbert software will then treat this folder as if it *were* a memory card.
If your memory card can be used with the card reader under your operating system and is correctly mounted, you can then simply copy the contents of this folder onto the memory card. This feature is intended for cases where the mount directory of the memory card does not work for any reason, and when alternatives such as “Sox” also fail.
The new hörbert 2021 has been continuously tested in our workshop at medium volume using high-quality AA batteries.
In standard mode – meaning playback from its SD card – hörbert runs for approximately 38 hours.
The older standard model of hörbert 2011 – without additional modules such as a sleep timer or Bluetooth module – was the top performer in the Stiftung Warentest test in November 2019.
In their test, it achieved 56 hours of playback time, while in our in-house tests it reached approximately 50 hours.
With a built-in sleep timer module (automatic shut-off), the playback time is reduced by a few hours.
With a built-in Bluetooth module, the playback time is reduced by up to one third of the standard model’s duration, resulting in around 35 hours.
Would you like all the new features such as Bluetooth, internet radio, voice recordings, sleep timer, and pause function
for your own hörbert as well? No problem! Starting from spring 2023, we are once again offering upgrades carried out by us.
However, hörbert 2011 must be sent to us for the upgrade.
Please contact us via the contact form so that we can provide you with an upgrade offer.
Visual differences:
The new hörbert comes with a slightly updated appearance and completely new internal electronics.
New features:
Proven and still included:
Due to the very high power consumption of these cards, interference noises may occur in the Bluetooth module during standard playback mode.
This does not happen with the cards we supply. We therefore recommend using the original hörbert memory card, as your hörbert will also run longer with it.
A Transcend card tested by us (16 GB Class 10) had significantly higher power consumption than our original cards.
This is, of course, detrimental to battery life.
If you do not want to give up your memory card, please contact our support team (service@winzki.de), as we can upgrade your hörbert circuit board for a small service fee so that even power-hungry memory cards can be used with minimal interference.
In general, the following applies: unfortunately, we cannot guarantee the functionality of third-party cards, as manufacturing methods and internal components can vary greatly and change frequently. We source our own memory cards directly from the manufacturer according to our specifications.
It is possible to change the name of paired devices in your Bluetooth transmitter.
You can find the necessary tips under the links below, depending on which device you are using:

The strength of electromagnetic radiation depends on the transmission power of the devices.
The performance class of the hörbert Bluetooth module corresponds to Class 2. This means: our Bluetooth connections are all Class 2 with a transmission power of up to 2.5 mW (+4 dBm).
Due to its very low transmission power, the hörbert Bluetooth module definitely complies with the recommended SAR limits.
This depends on the environment, for example whether there are obstacles such as walls or barriers in the way. However, the range is typically around 15 meters.
In hörbert mode, you simply listen to content with your hörbert as usual. Just switch it on, and it starts playing. Your hörbert with a built-in Bluetooth module will consume slightly more power in this mode than the standard hörbert, and therefore it will not reach the 50-hour runtime. This is because the audio has to pass through the Bluetooth module, which also requires some power. The playback time is therefore approximately one third shorter.
This faint humming, which is usually only noticeable during quiet moments and only in piano mode, is due to the fact that the audio has to pass through the Bluetooth module.
Interference noise can be minimized if all cables leading to the Bluetooth module are twisted together first, as shown in the installation video and in the installation instructions.
Note: Interference noise may be stronger if memory cards other than our original ones are used, as some cards draw more power than others.
hörbert arrives ready to play.
Depending on your selection, it comes with a preloaded memory card containing either German, international, or Swiss German audio content for children. If you choose a barrier-free hörbert, you can also select an empty SD card or one with audio content for adults. The hörbert for seniors automatically includes the free adult content card.
This means you receive over two hours of selected songs and stories right away.
We also include 4 AA batteries so you can start using hörbert immediately after unpacking it.
You can also use 4 rechargeable AA batteries in hörbert’s battery holders.
Important note:
If you purchase a hörbert with optional USB port and battery charging function, it is also delivered with a preloaded complimentary memory card of your choice.
However, to operate it via a power outlet, you will still need the following accessories:
If you would like to use hörbert on the go, you will additionally need:
You can find everything about hörbert’s USB port HERE.
We arrange this with you on a case-by-case basis: after all, it depends on what is broken, and we determine that, for example, via email, by phone, or at the latest in our workshop. Some repairs can be carried out by you if you wish, while others we prefer to handle here in our workshop.
We always work with you to find the most cost-effective way to get your hörbert ready to play again.
If you live in Switzerland, Liechtenstein, or the UK and need to send your hörbert from there, please contact us beforehand and do not send it without a return label from us, otherwise it may get held up at customs.
If hörbert needs to be sent to us for repair, we will of course try to preserve everything as much as possible.
As long as the decorated part is not damaged, we will only repair the rest, and you will receive your own hörbert back.
Please note that hörbert’s frame and front panel form a single unit. Individual parts cannot be replaced separately, as this would not be good for stability.
You can replace the handle, the speaker, the on/off switch, and the volume control (on the hörbert 2011), and in exceptional cases—after consulting with us—even the circuit board yourself, provided you have sufficient technical know-how and the necessary tools at home. If this is not the case, please contact us so that we can assist you.
A housing replacement (i.e. replacing the frame and the front while reusing all intact hörbert components) is generally carried out only in our workshop, as we may also perform necessary minor repairs and replace small parts—of course at a previously agreed flat rate, with the occasional screw included free of charge.
If batteries leak, you will find traces of battery chemicals on the electronics (circuit board). These traces must be completely removed to get your hörbert working again.
Important safety instructions:
Pay attention to your safety and that of your surroundings during the following steps! Only work with safety goggles! Only work with protective gloves! Do not touch anything else with the gloves! Work with an open window and sufficient fresh air! Do not work near flames or ignition sources! Keep chemicals and tools away from children! These instructions do not apply to other devices! Leave the repair to us if you do not feel confident performing any step! Risk of injury: Splashes of alcohol or battery chemicals in the eyes can cause serious eye injuries. In case of an accident, consult a doctor immediately. Working with high-proof alcohol can cause fires. Keep extinguishing agents ready. Alcohol can dry out your skin, so wear gloves! And again: keep children away from chemicals and tools!
There are two possible causes: either the contents of the memory card have become disorganized and hörbert can no longer read the card, or residues from leaking batteries are affecting the electronics. (In that case, continue with: Problems with leaking batteries?)
2. Next comes formatting:
On Mac: Applications->Utilities->Disk Utility
On Windows:
3. After successful formatting, please start the hörbert software, read the card again, and reload it using the hörbert software. You can use the data from your backup or—better yet—retrieve the data again from the original storage location on your hard drive.
We hope these steps solve the issue and are happy to assist with any further questions.
WARNING! This tip does not apply to hörbert 2011 models with a Bluetooth module. Please do not move the switch back and forth if your hörbert has a built-in Bluetooth module.
hörbert has a very robust on/off switch. The switch manufacturer applies a small amount of grease inside the switch. If this accumulates in the wrong place, it can cause this effect. However, this is not a problem: simply switch the button on and off at least 50 times very quickly and firmly. This will redistribute the grease and resolve the issue.
Background information: In a lamp, the grease would simply burn off with a spark, but such energy does not occur in hörbert. Therefore, some mechanical action may be required. You can switch it back and forth as quickly and vigorously as you like. The switch can handle it: we deliberately chose an oversized switch that can withstand children playing with it.
Yes, the hörbert software has also been available for Linux since 12/2020 (tested on Ubuntu >16.0.4) and can be downloaded here:
https://www.hoerbert.com/service/downloads-und-bespielen/
Otherwise, if necessary, it is also possible to manage without the hörbert software:
The audio files must be in WAV format with a 32 kHz sample rate, 16 bit, mono.
Using the tool ’sox’, you can use the following command line for conversion.
Which files your ’sox’ program can read depends on the compiled-in options.
sox --buffer 131072 --multi-threaded --no-glob inputFileName --clobber -r 32000 -b 16 -e signed-integer --no-glob outputFilename.WAV remix - gain -n -1.5 bass +1 loudness -1 pad 0 0 dither
One of our customers wrote a script that can also handle multiple files.
You are welcome to use or adapt the script if you like. However, we do not provide any guarantee regarding functionality or the absence of errors.

You can find sources for the artists and publishers here by clicking on the detailed content description for each memory card: hörbert’s preloaded content
In addition, there is a wide range of content available for purchase as MP3 or M4A downloads that you truly own. You can find these, for example, on Amazon and iTunes under the category “Music Downloads”. There you will find not only music, but also stories available for download.
Approximately 50 hours of audio content can fit on the included 4 GB memory card of the new hörbert 2021 model when using MP3 files.
Our free cards, which are included as part of the product, are already preloaded with over two hours of children’s songs and stories. You can supplement our content at any time with your own favorite songs and stories or replace it entirely.
More information on loading your own audio content onto the memory card.
If you own a “hörbert 2011”, the included 4 GB memory card can hold about 1000 minutes (or 17 hours) of content.
From our experience, even with these 17 hours, it can take several weeks to months before a child wishes for some variety.
Yes. The current hörbert model supports SD cards with capacities between 4 GB and 512 GB.
Here’s how it works:
You can format your SD card using your computer’s built-in tools. If FAT32 is not available, you can also choose FAT, EXFAT, or MSDOS-FAT.
Alternative without a computer:
Create 9 folders (0–8) in the root directory of the SD card for playlists.
Note: For a hörbert with 3 buttons, create only folders 1, 6, and 8.
You can now copy audio files into these folders (mp3, wav).
Playback order is determined by file naming, e.g.:
1_Title
2_Title
3_Title
Then safely eject the card and test it in hörbert.
If your hörbert has Butterfly firmware, you can transfer files via Wi-Fi using Browser Set Mode.
Select a playlist button → “Playlist content” → “FILE” to upload audio.
Note: After editing in Browser Set Mode, a playlist.m3u file is created to control playback order. New files added later via computer will be appended alphabetically.
Full guide: Instructions for hörbert with Butterfly firmware
For hörbert 2011:
Supports SDHC cards between 4 GB and 32 GB.
Recommended: Class 4 or 6.
Some Class 10 cards may cause occasional playback interruptions.
For both models:
Third-party cards may consume more power than the original hörbert SD cards. Compatibility may vary due to different internal components.
To ensure FAT32 formatting for hörbert 2011, use the hörbert software, which will also create the correct folder structure.
No need to worry: it simply isn’t getting enough power because the batteries or rechargeable batteries are empty. Just replace them with fully charged ones, and it will work as usual again. It is important to always use 4 equally charged cells—never mix batteries with unknown charge levels.
By the way, we strongly recommend using rechargeable batteries to protect the environment. At the time of delivery, we cannot know which charger you use, so we include regular batteries once to ensure hörbert is ready to use right away.
You can find everything about hörbert’s features HERE in our guides and videos.
In short:
Each colored button represents a full playlist with multiple tracks.
Each time you press the same button again, hörbert jumps to the next track within that playlist.
For example, if you press the red button 4 times, you will hear the 4th track of the red playlist.
If you switch playlists (e.g. press the yellow button), the new playlist always starts from the first track.
To jump back to the beginning of a track, press the black button at the bottom left once.
Pressing it twice takes you one track back within the playlist.
The gray button at the bottom right allows you to fast-forward within a track to find a specific position.
You can find everything about hörbert’s features here in our guides.
Details about the function of the black and gray buttons can be found in this FAQ:
hörbert is a natural product, which means we cannot control the color or grain of the wood. Each device is therefore unique! Small color variations, knots, and natural wood structures, as well as slight marks from the high level of handcrafting, are normal and unavoidable. We use only clear varnish so that the natural wood surface remains visible. We do not use plastic veneer or laminates!
The answer is both yes and no.
The standard hörbert is a portable device and does not have a power supply connection. It runs on 4 AA rechargeable batteries or standard batteries, which are available everywhere. A mains power connection is intentionally avoided so that hörbert remains safe for even the youngest users, fully mobile, and free from risks associated with cables or electrical outlets.
However, since November 2024, there are also hörbert for seniors and barrier-free hörbert models. In these cases, it is often necessary to operate hörbert using mains power. Therefore, these models come with a USB connection and battery charging function as standard.
For the children’s hörbert, you also have the option to add a USB connection and suitable rechargeable batteries when purchasing.
The USB-C connection is only available with the hörbert 2021 model (without toggle switch). The device must also have the Butterfly firmware installed.
Learn more about the USB-C connection in our BLOG ARTICLE ABOUT THE USB CONNECTION.
Does hörbert have a USB port?
Yes, but not for USB sticks. It is used to operate hörbert via a USB-C cable and a USB power adapter connected to a wall socket. If rechargeable batteries are inserted inside the device, they will be charged at the same time while hörbert is connected via USB-C. A very practical feature. MORE INFO ABOUT THE USB CONNECTION
Where is the audio content stored? hörbert works with an SD card.
You need an SDHC card reader on your computer to add your own content or make changes to the SD card.
Alternative without a computer and SD card reader
Since the end of November, the Butterfly firmware for all hörbert models from October 2021 is available. This applies to models with a rotary knob for power on/off. It allows you to manage settings and add audio files or web radio URLs via the Browser Set Mode, a convenient web interface.
Important note:
For the new hörbert 2021 model with Butterfly firmware (release October 2024), you no longer need the hörbert software to load content onto the SD card. You can do this conveniently via the Browser Set Mode or by copying your own files directly onto the SD card using your computer’s file manager.
Learn more in this BLOG ARTICLE.
For the older hörbert 2011 model with toggle switch, the hörbert software is required.
There is also an upgrade option to convert your hörbert 2011 to the new version.
The software is included on the memory card of a new hörbert. However, as we cannot guarantee it is the latest version, we recommend downloading the newest version here:
System requirements:
hörbert supports the following common file formats: mp3, wav – with the limitation that DRM (Digital Rights Management)-protected files will not work. DRM-protected content from (streaming) services such as Audible or Deezer is copy-protected and cannot be played directly on hörbert.
However, the current hörbert model offers the possibility to record Bluetooth streams while they are being played. This allows you to obtain new audio content by pairing hörbert with your smartphone, streaming playlists from services like Spotify, Deezer, or Audible, and recording them simultaneously.
In addition, the new hörbert can be used as a radio for internet radio streams. These can also be recorded directly onto the memory card while listening.
Learn more about the recording features of the hörbert 2021 model.
See also our article on adding your own content to hörbert’s memory card.
The wood, controls, and electronics of hörbert are selected and manufactured in such a way that neither the device nor the child will be harmed, even during rough use. hörbert is built to experience a lot and may develop a few “dings” over time, which can easily be smoothed out with fine sandpaper if needed.
If hörbert should ever fall and something breaks, spare parts are available—because throwing it away is not an option. Of course, you can also send your hörbert to us for repair at any time; we’ll be happy to advise you.
Of course, in our online shop. If you prefer ordering via Amazon, we also offer hörbert there (although it’s not faster than ordering directly from us, as we handle the shipping in both cases).
hörbert is also available in selected retail stores in Germany, Austria, and Switzerland. You can find a list of retailers here. Some of our retail partners can also arrange custom engraving requests for you through us.
hörbert is designed so that even young children from around the age of 2 can independently listen to music and audio stories—whenever and wherever they like.
Using the on/off switch and the colorful buttons to select songs and stories is very easy.
Only uploading new content requires an adult’s help. However, a new hörbert already comes with many songs and stories included, so you don’t need to spend your first time with hörbert at the computer.
We do not specify a strict age limit for hörbert. Children can usually operate it independently from around the age of 2, as they typically have the motor skills needed to press the rotary knob for switching on/off and to use the colorful buttons on the front.
…and if seniors would like to enjoy their favorite music on a beautiful and easy-to-use device, hörbert is also the perfect audio player for them.
Tip: For very young children, it is recommended to activate the volume limit on hörbert.
You can find everything about hörbert’s features here.
A CD with copy protection can usually be identified by the corresponding IFPI copy protection logo. It is a black circle with a white triangle. You can find more information here:
https://de.wikipedia.org/wiki/Kopierschutz
Tip:
It is recommended to first import a CD into your computer using a program like iTunes. This makes transferring the files to hörbert’s memory card much faster. In addition, iTunes has a good converter that automatically converts tracks into an optimal format (m4a or preferably mp3).
On Windows, you can do something similar with Windows Media Player, but make sure to select the mp3 format, as hörbert software cannot read .wma files.
After importing into iTunes, you can use the hörbert software to drag and drop tracks directly from your iTunes library into the desired playlist window.
Software is necessary to conveniently organize tracks into playlists and in the correct order. If you simply copied MP3 files onto a memory card, the player would not know in which order to play them or which button should trigger which playlist.
Another advantage is that you can also use source files in formats such as OGG, WAV, or FLAC, as well as directly import from audio CDs or other common formats—something most MP3 players cannot handle.
Instead of describing hörbert as an MP3, OGG, WAV, and FLAC player, it is categorized simply as an “MP3 player.” Otherwise, you wouldn’t even find it in most shops, as there is usually no category for “audio players,” only “MP3 players.”
Strictly speaking, the correct term would be “universal audio player for children.” However, to make it easier for customers searching for such a device, we use the term “MP3 player” as a general category—even though hörbert can do much more.
If you own a “hörbert 2011” model (the predecessor of the current hörbert), all audio formats you transfer are automatically converted to .wav format by the hörbert software. This conversion helps save a lot of power during playback, because decoding MP3 or other formats continuously requires more processing power and therefore more energy. By doing this conversion once on the computer, hörbert can work with already decoded files and achieve longer battery life.
Another advantage is that you can use source files in formats such as OGG, WAV, or FLAC, as well as directly import from audio CDs or other common formats—something a typical MP3 player cannot handle.
And here’s the key point: since the hörbert software is needed anyway to organize files into the correct playlists and order, it can also perform all necessary conversions automatically—without any extra effort from you.

M4A files can be played on a hörbert with a toggle switch if they are transferred using the hörbert software. The display showing a duration of 0 minutes is a technical issue that occurs only once per file during transfer and does not persist afterward:
Before transferring, the file is shown with a duration of 0 because the hörbert software cannot determine the length of M4A files prior to conversion. The file is still transferred correctly.
After reinserting the memory card, the correct duration will be displayed in the playlist.
Tip: If it is an older .m4a file with copy protection (e.g. from 2003–2014), it cannot be transferred to hörbert. In this case, you need to download the file again without DRM. Apple offers a “replacement” option for such files: https://support.apple.com/en-us/HT201616
If your hörbert 2011 remains silent after switching it on, please check the following in this order:
If this does not solve the issue, please continue here: hörbert does not switch on or turns on/off by itself
Is the problem still there?
If a screw is loose, you can carefully tighten it yourself. This issue may occur due to changes in humidity or temperature, as the wood can expand or contract slightly.
Is the problem still there?
Please contact our support team via the contact form.
Is it possible that you are using a particularly fast Class 10 (or faster) SD card?
With some of these cards, this issue can occur. They occasionally perform internal housekeeping or sorting processes, which can interrupt the data stream. As a result, the problem does not occur at a specific track or playback time—the card’s microcontroller sometimes “does its own thing.”
If possible, please test with a smaller/older/slower card (e.g. Class 4 or 6). In that case, the issue should no longer occur.
Tip: If possible, use Class 4 SDHC cards between 4 and 32 GB. Our supplied cards are Class 4, identifiable by a “4” inside a circular “C”.
Yes. Small dents or scratches can even be fixed yourself using fine sandpaper. Larger damage is best repaired by replacing the affected parts to ensure stable and safe operation afterward.
For more extensive repairs, you are welcome to send your hörbert to us after prior arrangement. A complete housing replacement (i.e. replacing the frame and front while reusing all intact parts) is carried out exclusively in our workshop, as we may also perform necessary minor repairs—of course at a pre-agreed flat rate.
