How it works:
CROS stands for ‘Contralateral Routing of Signal’ and consists of two parts:
The CROS aid with a microphone to pick up sounds and voices from the non hearing ear and wirelessly transmit them to the hearing aid.
The hearing aid to receive the signal from the non hearing ear and play it to your good ear CROS II will transmit sound and voices to let your good ear hear for both your ears. If you have good hearing in one ear and impaired hearing in the other, then CROS II will work for you.
