Hearing loss in one ear

The smart solution for single-sided hearing

You know the situation: you’re in a noisy room and can’t hear your partner or colleagues because they’re not positioned on the side of your good ear, or you are on the phone and unaware of your environment. If this sounds familiar, Phonak CROS B is the smart solution for you.

How it works

CROS stands for ‘Contralateral Routing of Signal’ and consists of two parts:

the CROS device with a microphone to pick up sounds and voices from the non hearing ear and wirelessly transmit them to the hearing aid
the hearing aid to receive the signal from the non hearing ear and play it to your good ear

CROS B will transmit sound and voices to let your good ear hear for both your ears. If you have good hearing in one ear and impaired hearing in the other, then CROS B will work for you.

Wherever you want

Enables you to have a conversation in quiet and noisy surroundings without having to reposition yourself.

Just switch it on

Requires no surgical procedures. Simply switch it on and enjoy hearing from both sides.

Almost invisible

So small and discreet you can wear it without it being noticed.

CROS II will transmit sound and voices to let your good ear hear for both your ears.

The discreet wireless solution for children

Roger™ Focus is the digital behind-the-ear receiver based on the Roger wireless technology. It consists of two parts:

a behind-the-ear receiver worn on your good ear which receives the signal streamed from any Roger microphone
a Roger microphone which picks up voices and sends them directly to the Roger Focus and into your ear
