App Features


When you first start the mobile app and connect to your device, you will be given the option to personalize or select from 3 presets.



In this screen you are presented with tones to personalize your device to your exact hearing needs. The noise level of your surroundings are monitored to make sure that the process is accurate.


If you prefer, you can select from 3 presets rather than personalize.


In this screen, you can select environmental settings to match your needs at the moment. You can select from Everyday, Restaurant, and Entertainment.


Here you have more advanced control over your sound. In addition to the volume, you can adjust the bass, mid and treble ranges separately.
