Product archive – Information about older hörbert models

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.

hoerbert 2021

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.

Questions about hörbert

Your hörbert has fallen on the encoder? If you are confident enough to repair it yourself, you will find the instructions below. If you cannot repair the encoder, it is also available as a spare part in our shop. You can order it and replace it yourself with the help of the instructions below. If you don’t want to do it yourself, you can of course send hörbert to us for inspection and repair.

Please be sure to contact our service team in writing beforehand to receive a ticket number and the corresponding return instructions.
 
Encoder removal guide:

  • Loosen the rotary knob on the encoder with a 2mm hexagon socket/bus
  • Loosen the nut under the knob. You will need an 11mm wrench/socket for this. 
  • Then pull the encoder out of the mounting hole and loosen the release from the ribbon cable on the encoder itself. To loosen the release, you have to push the two protruding black lugs on the right and left of the cable with your fingernails. Then carefully pull out the cable.
  • The ribbon cable can get stuck in the board on the other side.
  • Remove the encoder and carefully try to straighten it again.
  • If this does not work, order the spare part from our shop or send it to hörbert by arrangement.

 

Install repaired or new encoder:

 

  • Plug the cable into the encoder. Make sure that the cable is plugged in as shown in the picture and that the blue side is not inserted with the wrong polarity. The white side must be at the top.
  • Push the release on the cable shut:

  • Insert the encoder into the mounting hole of the housing and put on the nut.
  • Tighten the nut with the 11 mm spanner.
  • Put on the rotary knob – with a distance of approx. 1 mm to the housing – and tighten it with the grub screw and the 2mm hexagon socket. Done!

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.

Cleaning after leaking batteries:

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!

And so it goes:

  1. Pull the memory card out of the memory card holder. Check the contacts on the memory card. It may need to be replaced when it has received battery chemistry. You can try cleaning them with alcohol.
  2. Remove the electronics by loosening the 4 nuts on the board. Lift up the board and disconnect all 3 cables.
  3. Find all traces of battery chemistry on the top AND bottom of the board. You’ll need to clean it very carefully to stop the corrosion.
  4. Use plenty of isopropyl alcohol 70% (e.g. from the pharmacy): Drip the alcohol abundantly on all places where you find traces of battery chemistry. Soak everything. If the alcohol evaporates, drip more of it onto the board, even into the memory card holder.
  5. Use your toothbrush to scrupulously remove all traces of battery chemistry. Cotton swabs can also help. Important: NEVER scratch! Because if you scratch a trace or destroy a small component, it is very likely that the board is finally broken.
  6. When everything is clean, let the alcohol evaporate for an hour. Never use the electronics in wet condition.
  7. Now you can plug all cables back in where they were, insert the board again and screw it tight.
  8. Now insert the batteries and the memory card again and switch on audibly. Don’t forget to breathe.

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.

hoerbert 2011

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.

Questions about hörbert 2011

Please 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.

  1. The toggle switch for turning it on/off is no longer present. Instead, the volume control knob can be pressed for electronic on/off.
  2. For the voice microphone, the front panel of hörbert now has a small opening at the bottom right, behind which the microphone is located inside.
  3. The new hörbert uses even less plastic! The colored buttons are now also made of wood.

New features:

  • Recording function:
    All sources that hörbert supports can also be recorded onto the memory card: voice recordings via microphone, Bluetooth streaming, and internet radio.
  • Microphone:
    Record speech and music in CD quality with the microphone and play it back directly from the memory card.
  • WiFi for internet radio:
    Connect hörbert to your Wi-Fi to play internet radio stations using hörbert’s buttons. With the recording function, radio broadcasts can be recorded and later played back from the memory card.
  • Pause function:
    hörbert resumes playback exactly where you turned it off. Fast-forwarding to the correct position is no longer necessary. However, if you select a different playlist, hörbert always starts with the first track of that playlist.
  • Even less plastic
    The colored buttons are now turned wooden parts. hörbert now contains less than 5% plastic. Only the circuit board and its components remain. This cannot be further reduced.
  • Even more space for reloading
    The storage space on the SD card now goes further, as hörbert can play native MP3 files. This means more hours fit on the same card. Each of your memory cards can hold up to five times more content compared to the previous format. When using MP3 files, approximately 50 hours of audio content fit on the included 4 GB card.
  • Bluetooth audio for headphones and streaming
    You can use hörbert with Bluetooth headphones or as a Bluetooth speaker. Simultaneous listening with up to two wireless headphones is possible. With a phone or tablet, you can stream content from services such as Spotify or Audible to hörbert.
    This is already possible with your “hörbert 2011” if you have a built-in Bluetooth module.
    What’s new is that everything hörbert plays as a Bluetooth speaker can also be recorded, so it can be replayed later from the memory card.
    Also new is that you no longer need to pay extra for Bluetooth functions. Bluetooth audio is now included in the price. Of course, the Bluetooth function can also be completely disabled if you prefer no wireless signals.


Proven and still included:

  • Sleep timer included
    Set how long hörbert should play before it switches off automatically.
  • Selectable additional volume limit included
    piano/forte

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.

  1. Please first check the following: Does hörbert play normally in standard hörbert mode through its built-in speaker when you switch it on? If so, the module has at least been installed correctly.
  1. To use hörbert with a built-in Bluetooth module as a Bluetooth speaker, you need to switch it on using the toggle switch and then immediately switch it off again. IMPORTANT: please leave hörbert switched off and DO NOT switch it on again. The LED indicator inside the Bluetooth module will now blink twice per second and a signal tone will sound, indicating 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.
    Now start a playlist on your phone to play it through hörbert.
  1. Your phone shows a connection to hörbert, but the playlist is not played through hörbert, instead it plays through the phone.
    – Proactively remove hörbert from the list of Bluetooth playback devices on your phone (e.g. using the command “Forget this device”) and let your phone search for hörbert again and pair with it.
    – Is there perhaps a setting in your phone or directly in the app that causes the phone to be used as the playback device instead of hörbert? If you are unsure, check your phone’s settings or documentation.
  1. Is another Bluetooth device “grabbing” the connection to your phone? For example, switched-on Bluetooth headphones, a smartwatch, a tablet, or a neighbor’s device? Please disconnect these devices first and/or move to a different location. It is recommended to turn off Bluetooth on nearby devices or switch them off completely before pairing with hörbert.
Pairing headphones with hörbert for the first time can take up to a minute, especially if there are many other Bluetooth devices nearby. It is recommended to switch off other Bluetooth-enabled devices or disable Bluetooth on them before pairing. The headphone mode only searches for headphones during the first 60 seconds after hörbert is switched on. In headphone mode, hörbert’s speaker switches off as soon as sound is heard through the headphones. If it doesn’t work on the first attempt, it often works on the second (or third). Please proceed with troubleshooting as follows:
  1. Do the headphones work with other Bluetooth devices, for example, can they be successfully paired with a Bluetooth phone? If not: please fully charge the headphones first. If they still do not work, contact the retailer where you purchased the headphones. There may be a defect, and the headphones may need to be replaced.
If yes: proceed to steps 2 to 6:
  1. Are switches 5 and 6 (Bluetooth and pairing) on the Bluetooth module activated? Please only operate any switches on the “DIP switch” of the Bluetooth module when hörbert is switched off. If switch no. 6 (pairing) is deactivated while hörbert is switched on, all stored pairings may be deleted under certain conditions. (See section 3.2.4.2 of our Bluetooth module manual).
  2. Are other nearby Bluetooth-enabled devices trying to connect to the headphones? Please switch off Bluetooth on all nearby devices (e.g. phone, tablet, computer) and/or move to a different location.
  3. If your headphones have their own volume control, remember that the volume may need to be increased there if you cannot hear anything. Also ensure that hörbert’s volume control is not set to very low.
  4. If pairing does not work after one minute, please switch off all devices and try the process again a second or even third time:
    1. Switch on the headphones. Bluetooth mode must be activated. Check for the correct LED indication or a voice prompt such as “Bluetooth/Pairing on” depending on your headphone model.
    2. Switch on hörbert by moving the toggle switch forward. The LED on the Bluetooth module must blink twice per second. hörbert will now search for headphones for 60 seconds. Please allow this full time before switching everything off and restarting the process if it does not work immediately.
If none of these tips help, our service team will be happy to assist you. Go to the contact form!
 

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:

https://link.hoerbert.com/6M00K

www.Techify.de (rename paired Bluetooth devices on Android):

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:

  • USB power adapter
  • USB-C cable

If you would like 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 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.

Cleaning after leaking batteries:

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!

How to proceed:

  1. Remove the memory card from the card holder. Check the contacts of the memory card. It may need to be replaced if it has been exposed to battery chemicals. You can try cleaning it with alcohol.
  2. Remove the electronics by loosening the 4 nuts on the circuit board inside hörbert. Lift the board and unplug all cables.
  3. Locate all traces of battery chemicals on both the top AND bottom of the circuit board. You must now clean them very thoroughly to stop corrosion.
  4. Use plenty of 70% isopropyl alcohol (e.g. from a pharmacy): generously apply the alcohol to all areas where you find traces of battery chemicals. Let everything soak. When the alcohol evaporates, apply more to the board, including into the card holder.
  5. Carefully scrub away all traces of battery chemicals with a toothbrush. Cotton swabs can also help. Important: NEVER scrape! If you scratch a circuit trace or damage a small component, the board will most likely be permanently damaged.
  6. Once everything is clean, let the alcohol evaporate for one hour. Never use the electronics while wet.
  7. You can now reconnect all cables, reinstall the circuit board, and screw it back in place.
  8. Insert the batteries and the memory card again and switch hörbert on. Don’t forget to breathe.

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?)

  • To narrow down issues with the memory card, you can, for example, try another compatible memory card for comparison, or first back up all contents of your hörbert card using your computer’s built-in tools: simply copy all contents of the memory card into a folder on your computer. You may need this backup later.
  • A disorganized memory card can most easily be “repaired” by formatting and reloading it:
    Here are the individual steps to do so:1. First, make sure to create a backup of the data on the card, as formatting will delete all contents. You can select the card as a drive in Windows Explorer or macOS Finder, mark all files, copy them, and save them in a new backup folder on your hard drive.

     

    2. Next comes formatting:

    On Mac: Applications->Utilities->Disk Utility

    • Use Spotlight search (shortcut: “cmd” + space) to find “Disk Utility”. Alternatively, it can be found in the “Utilities” folder.
    • The inserted SD card should appear on the left side. Select the SD card to be formatted and make sure it is the correct drive. All data on the card will be deleted in the next step.
    • In the center, you will see several tabs. Select “Erase”.
    • Then choose the desired format (FAT or FAT32 or msdos FAT) and assign a name to the SD card.
    • Start formatting using the “Erase” command.
    • After formatting, please eject the card properly before removing it from the computer.

    On Windows:

    • Open Windows Explorer. For example, press “Windows” + “E” at the same time.
    • You will see the SD card in the window. Right-click on it and select “Format”.
    • Select “FAT32” as the format. If not available, choose “FAT” or “msdos FAT”.
    • Disable the “Quick Format” option and click the “Start” button.
    • Confirm with “OK”. The SD card will now be formatted. Once the process is complete, close the windows with “OK” and “Close”.
    • After formatting, please eject the card properly before removing it from the computer.

    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:

Converting audio with sox

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

 

Bash script

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.

The publishers of the content included with your device offer even more beautiful music and stories – some of them even free of charge.

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.

Even more content for your hörbert, mostly free of charge, can be found here on our website

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.

Required preparation steps for the SD card so that hörbert can play it

  • Your SD card must be formatted in FAT32 (or FAT, MSDOS-FAT, EXFAT).
    Important: Formatting will permanently delete all data on the selected storage medium. Make sure you are formatting the correct card and that you have created a backup or no longer need the stored data.
  • You must then create 9 playlist folders named 0 to 8 on the SD card.

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:

  • Start the Browser Set Mode
  • Go to GENERAL → Advanced Settings
  • Enable “Expert Menu”
  • Navigate to EXPERT → Memory Card
  • Format the SD card there
  • Add files or web radio URLs under PLAYLISTS
  • You can also add podcasts (via Butterfly2 firmware)
  • Or exit Browser Set Mode and continue editing via computer

Set up SD card on a computer and transfer many files quickly

1. Create folder structure

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.

Editing via Browser Set Mode (without computer)

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.

How do the colored buttons on hörbert work?

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:

hörbert Software Download

System requirements:

  • PC or Mac (Intel), operating system: Windows 10 or higher, macOS from version 10.14, Linux (tested on Ubuntu >16.0.4)
    If you are using an older system, please contact our support team.
  • Screen resolution at least 1024×768 pixels
  • At least 4 GB free disk space
  • At least 2 GB RAM

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.

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.

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:

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:

  1. Is the device switched on? (Toggle the switch back and forth once.)
  2. Is the memory card properly inserted into the card slot?
  3. Is the volume turned up? (Turn the knob fully to the right for testing.)
  4. If you hold your ear close to the speaker at full volume: do you hear a very faint rhythmic chirping sound? (If yes, continue with: Only faint rhythmic sounds can be heard)
  5. Are the batteries empty? Insert a completely new set of 4 identical batteries from the same fresh pack. If necessary, try another new pack, as it can happen that one weak cell is included or batteries are already empty when purchased.
  6. Do the batteries have proper contact? Check whether all battery clips are touching the metal ends of the batteries correctly. If necessary, gently bend the contact springs inward (with batteries removed).
  7. If your hörbert 2011 has an automatic shut-off module installed: is exactly one of the small white DIP switches (1–6) set to the down position?

If this does not solve the issue, please continue here: hörbert does not switch on or turns on/off by itself

  • Please first insert a completely fresh set of new batteries or fully charged rechargeable batteries, as poor power supply can also result in distorted sound.
  • Next, we should rule out simple causes such as a loose screw or a vibrating back panel that may just need tightening.
    Remove the sliding back cover and listen to the device at full volume with the back open to check if the humming noise is still present.

Is the problem still there?

  • If yes, try placing your hand on the speaker grille to check whether the noise comes from the grille or the wooden frame around it (possibly due to one of the four screws being loose).

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.
