Phonak Binaural VoiceStream Technology™

Everyone knows that hearing with two ears is better than one. It's not just common sense, it's supported by scientific research.1-3

All ages can benefit from listening with two ears. It makes it easier to understand speech in noisy environments and to determine where sounds are coming from.

Cochlear implant recipients hear with both ears in two ways -- either bilaterally (with a cochlear implant in each ear) or bimodally (with a cochlear implant in one ear and a hearing aid in the other). Only AB and Phonak go beyond bilateral and bimodal hearing with Binaural VoiceStream Technology™.

Groundbreaking Technology

The groundbreaking Phonak Binaural VoiceStream Technology™ in your Naída CI sound processors doesn’t simply process sounds independently, like other systems. It gives your processors the unique ability to communicate with each other.

Your processors work together, automatically and in real time. They intelligently focus on the sound you want to hear and deliver it wirelessly to both ears simultaneously, while significantly reducing unwanted noises. As a result, you get the maximum possible speech understanding in any environment.

StereoZoom feature

enables the microphones on both processors to work together to focus on the speaker directly in front of you to improve understanding in extreme noise.

ZoomControl feature

allows you to effortlessly focus on a speaker in front of, beside, or behind you.

DuoPhone feature

automatically streams calls from any kind of telephone to both ears at the same time for easier conversations on the phone.

QuickSync feature

offers the unique convenience of one-touch control, so any volume or program adjustment you make on one processor is automatically applied to the other.
