Phonak Cros B

Wireless CROS device for single-sided deafness

  • StereoZoom
  • CROS Volume Control
  • AutoSense OS™
  • Real Ear Sound

If you can’t hear your spouse, friends, or colleagues when you are in a noisy room or a car because they are positioned closest to your non-hearing ear, or if you are on the phone and unaware of your surroundings, then the Phonak CROS B is the solution for you.  

CROS B will transfer sound and voices to let your better hearing ear for both ears. The CROS device has a microphone that picks up sounds and voices from the non-hearing ear and wirelessly transfers them to the hearing aid worn on the other side. The hearing aid receives the sounds from the non-hearing ear and plays them to your better hearing ear. This allows you to follow conversations in quiet and noisy surroundings without having to reposition yourself.

Once CROS B is fit with a Belong hearing aid, simply switch it on and hear sounds and voices clearly from both sides.


Enjoy Hassle-Free Hearing
Using Binaural VoiceStream Technology™, CROS B wirelessly transfers the sound from the poorer ear to the hearing aid on the better hearing ear, delivering much better speech understanding in the background noise.

CROS B can also focus on a single voice in a crowd and reduce background noise thanks to the StereoZoom feature. As a result, it streams less noise to the hearing aid on the other side improving speech understanding. (only available in B90 and B70 performance levels).

Phonak’s cutting-edge AutoSense OS™ operating system seamlessly adjusts to the listening environment.

CROS B - Rechargeable (Now Available)
The CROS B-R provides you with all the proven benefits of Phonak CROS in a rechargeable option so you can enjoy a full day of hearing from both sides with no battery hassles*.
