Phonak CROS B - Evolve Hearing Center

Invisibility to explore life's rich soundscapes with confidence

Phonak CROS B is based on Phonak Belong technology. When CROS B is fit with a Belong hearing aid, it enables you to hear sounds and voices clearly and follow conversations from any direction. Using Binaural VoiceStream Technology from Phonak, CROS B wirelessly transfers the sound from the poorer ear to the hearing aid on the better hearing ear. As a result, CROS B delivers much better speech understanding in background noise.

What makes Belong hearing aids so special is a unique operating system called AutoSense OS™. It senses your surroundings and adjusts your hearing aids every step of the way. Just turn them on and the rest is automatic.

It doesn’t matter where you are or what you’re doing, CROS B and Belong hearing aids were created to simplify your life.


  • Understanding in noisy places. Zoom in on a voice and reduce background noise to hear what you want.
  • Understanding while driving. Understand your travelling companions with ease as CROS B streams to your good ear.
  • Understanding while out-and-about. Improve the awareness of your surroundings and hear sounds from both directions.
  • Easy to use. Simple and ready to use - just switch it on and enjoy hearing from both sides.
  • Stylish and discreet. Your friends and family will notice your improved hearing much more than your CROS device.
