Phonak CROS - Features & Benefits

The main challenge of developing a sophisticated CROS solution is integrating the input from the Phonak CROS Transmitter while keeping important benefits. Thanks to the latest Spice technology, Phonak CROS boasts a wealth of impressive features which address clients’ listening comfort and usability needs.


Traditionally, CROS/BiCROS solutions did not offer the benefits of automatic functionality. Phonak CROS offers full access to the industry benchmark - SoundFlow. This multi-base automatic program seamlessly adapts and integrates the right set of parameters and sound cleaning features to ensure optimal listening for every sound environment. The streamed signal from the Phonak CROS Transmitter and the hearing instrument signal undergo the same SoundFlow signal processing. Both signals are simultaneously optimized to the changing environment in real time.

Real Ear Sound

Placing a device with an omnidirectional microphone behind the ear alters natural localization based on intensity and frequency cues. This is problematic for individuals with hearing in one ear who must rely only on monaural localization cues, as they already struggle to localize sounds. Real Ear Sound uses discrete high frequency directivity to simulate the effect of the unobstructed pinna. This benefit is now available, for the first time, to CROS/BiCROS wearers.


Sophisticated, one-touch control adds convenience to manual adjustments and is an important option for many wearers. With one touch of the button on either the CROS transmitter or hearing instrument, QuickSync instantaneously synchronizes the volume or program settings. A Phonak CROS System can also be conveniently controlled remotely via myPilot or Phonak PilotOne.

Signal alerts

In the unlikely event of a connection interruption, a clear and distinct alert will be activated. In addition, separate battery status alerts for the Phonak CROS Transmitter and hearing instrument provide further security.


Housed in the popular M13 or M H2O style, the Phonak CROS H2O meets the industry’s highest standards for water and dust resistance, IP67*. Together with a WaterResistant Quest or Spice+ BTE or RIC on the better ear, it is the first ever WaterResistant CROS system. Clients can now enjoy all around hearing delight, no matter what the activity.
