As many of our hearing aids are battery operated, we offer high quality hearing aid batteries to ensure that the best hearing experience can be achieved.
Our batteries are all mercury free zinc air batteries. Zinc air batteries have a higher capacity-to-volume ratio (greater energy density) than other batteries. Nearly all cell systems must store all their reactive components entirely within the cell. Since zinc air uses oxygen from the air as a battery reactant, it frees a large amount of internal volume to allow for more zinc.  The more zinc means the longer the life.

Coselgi CROS products


For people who have unaidable hearing loss on one side, communication is often difficult, since they cannot be spoken to from both sides. With a CROS device sound is wirelessly routed from one ear to the other. The CROS system, which picks up the sound via the microphones, is worn on the unaidable side. The sound is transmitted wirelessly to the receiving device at the contralateral ear, where it is emitted in the ear with hearing.

Acoustic RC App

The Coselgi Acoustic RC app is compatible with all Coselgi hearing aids, except CIC-M devices. The Acoustic RC app works as a remote control for your hearing aids. With this app you can adjust the volume of your hearing aids and mute them. Changing the hearing program is another benefit of this app, as is adjusting the directional focus. You may need to do this if your hearing aids are focused on your front but you want to hear what is being said to your right.
