Phonak CROS Belong

Wireless CROS device for single-sided deafness including rechargeable

  • 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 the CROS B hearing aid is fit with another Belong compatible hearing aid, simply switch it on and hear sounds and voices clearly from both sides.
