Baha® Smart App: Frequently Asked Questions


Baha Smart App is compatible with the Baha 6 Max Sound Processor.


For an up-to-date list of compatible smartphones OS versions, please refer to www.cochlear.com/compatibility.


Yes, in most cases. The app is verified on the OS available at time of launch. If a newer OS version is reported to cause any issues, we will aim to update the app and resolve the issue as soon as possible.

To minimise the risk of problems with the pairing, connection or app when updating the OS, we recommend that you either:

  • log out from the app, unpair the sound processor and uninstall the app prior to updating the OS, or
  • log out from the app, unpair the sound processor, uninstall the app then restart your iPhone after you have updated the iOS.

Afterwards, start by pairing the sound processor, then download and install the app (see further instructions below) and log in again using the same details as before.


Yes, you can pair up to 5 smartphones to your sound processor(s) and have the app installed on all of them. However, you can only connect one smartphone at a time to your sound processor(s).


The app provides on-screen instructions on how to resolve issues with connection. Make sure are using the latest operating system (OS) (unless otherwise communicated from Cochlear on www.cochlear.com/compatibility). We recommend that you, prior to updating the OS, un-pair your sound processor and then pair again after the update.

Additionally, if you are streaming audio from your smartphone to the sound processor when the app is started, you can experience problems connecting. If the app is running in the background when audio is being streamed, this should not be an issue.


The connection between your sound processor and smartphone can be lost if the sound processor battery level is low or if the distance between the smartphone and sound processor is too great or blocked.

Make sure the sound processor has sufficient battery and is within range of the mobile device. Make sure Bluetooth is turned on and then restart the app. The app should automatically reconnect.


It is difficult to give an exact distance since this depends on factors such as sound processor battery level, any solid objects in-between, and the environment you are in.


The battery level on your sound processor may be too low to support the connection. Try to replace the battery. The app will reconnect automatically.

If you continue to experience problems, you could try to remove the paired sound processor from your smartphone, and then pair it again. See more under "How do I remove a previously paired sound processor"?


When you stream sound from your smartphone, the sound processors automatically move to a streaming program. In order to go back to a hearing program, stop the streaming operation.


You may have lost connection to your sound processor. When connection is re-established you can change program again.


The battery indicator in the app will show the current power level of your sound processor battery as full or low. Low battery strength means that wireless operation is close to interruption and that batteries should be changed soon.

The Baha 6 Max Sound Processor use a zinc-air battery, which provides almost the same level of power until it is nearly empty and then loses power very rapidly. It is therefore difficult for the app to display an accurate battery level until the sound processor provides a battery warning.


No. The app does not significantly impact the consumption of the sound processor battery. Running the app will take up some of the smartphone battery, similar to other apps.


Yes. If you pair your mobile device with your child’s sound processor, you can control and monitor it from a distance, but you need to be within range. This allows you to see battery status, adjust volume and change program without needing to touch the sound processor.
