Infinio
A rechargeable Phonak solution developed for users with unilateral hearing loss, transmitting sounds from the non-hearing side to the better-hearing ear wirelessly.

Open the Doors to a New Sound World
CROS Infinio detects sounds from the side of your non-hearing ear and transmits them wirelessly to your compatible hearing device in the better-hearing ear. This aims to reduce communication difficulties that arise depending on which side the sound is coming from.
