Health Data Tracking

Listening in noise and over distance

Roger is designed to improve hearing in situations where there is background noise and there is distance to the speaker. The microphone picks up the voice of the speaker and wirelessly transmits it directly to Roger receivers*** in your clients' hearing aids.

This enables them to fully participate in group conversations even in very noisy environments, such as restaurants, meetings at work and school activities. The proven performance of Roger6 streams directly to Phonak Slim.
