The RONDO 3 audio processor for cochlear implants has an integrated rechargeable battery. It can be charged wirelessly and lasts all day long. The battery status can be checked at the touch of a button on the device or via a smartphone. The processor is worn on one side of the head and not at the ear, which particularly benefits wearers of spectacles. A variety of different covers – from discreet to eye-catching – offers users the possibility of adapting the design to their personal taste.
