Phonak Cros B will transmit sound and voices to let your good ear hear for both your ears. It is the hearing aid for single-sided deafness. If you have good hearing in one ear and non-hearing in the other, then CROS B will work for you.
The Cros B will pair with any Phonak Audeo B range hearing aid, so you can have the same colour range as in the Belong family.
CROS stands for ‘Contralateral Routing of Signal’ and consists of two parts:
- the CROS aid with a microphone to pick up sounds and voices from the non-hearing (dead) ear and wirelessly transmits the sound to the hearing aid worn on the ear that hears
- the hearing aid to receive the signal from the non-hearing ear will play sounds it has had transmitted to your good ear
With the Cross B, it:
- enables you to have a conversation in quiet and noisy surroundings without having to re-positioning yourself
- allows you to respond to people when they talk to you on the side you can’t hear from
- requires no surgical procedures
- can be worn without it being noticed
Hearing Aid Style
The Phonak Cros B is available in 2 different styles dependent on your level of hearing loss, hand dexterity and personal preference.
