A free program for Android, by Bernafon AG.

The EasyControl app for Android is the only software application that makes it possible to control your hearing aid device from your Android phone. You can adjust volume, select and change tones, and change speech mode with a simple tap.

In addition, you can listen to the sound from any source and change the sound balance and filter settings.

The EasyControl app supports all devices that are compatible with the EasyControl-A protocol. The app allows you to select the hearing aid you want to control.

If you are using a mobile device, you can also access the Bernafon service on IFTTT.
