You can adjust the volume of your hearing aids through the Concha Labs app or on the hearing aid itself. In the app, go to the “home” page, select “volume” (under the battery percentages).
You may raise the volume by quickly pressing the top of the rocker switch on the device (less than half a second press), and lower the volume by quickly pressing the bottom of the rocker switch (less than half a second press). You can increase and decrease the volume by 6 clicks in either direction and with each click, you will hear a ping.
You can mute and unmute the hearing aid by pressing either the top or bottom of the rocker switch for one second or longer.
