Sleek, discreet design

Inductive charging makes it easy to securely place the hearing aids in the case for changing.

LED lights on the case display the power status and indicator lights on the hearing aids let you know that charging has begun.

With enough power for three full charges of both hearing aids, the portable case makes it easy to charge on the go.

Your patients can easily see the battery status of their hearing aids on the ReSound Smart 3D app and will get a notification when the rechargeable battery is running low.

Battery indicator

LED lights on the back of the portable charging case indicate the battery status of the charging case. LED lights on the inside of the charging case show the battery status of the hearing aids.
