You said: I have no hearing in both ears

If you have no hearing in either ear, you should consider cochlear implants for both ears. Compared to unilateral cochlear implants, bilateral cochlear implants provide unique benefits that make it easier to hear the world around you.1

The natural benefits of hearing in stereo

Hearing with two ears provides a more balanced and focused representation of sounds. With two cochlear implants, you can take advantage of the natural way that your brain interprets sounds and their location, making it easier to find and hear what you want to hear.2


Wear and go with swappable devices

The Naída CI sound processors are equipped to be used on either ear, so there’s no left or right side to consider. This makes it easy to wear and manage two devices.

“ It is much easier to hear in noisy environments. I am more confident in social situations.”
Jake M., AB Recipient

Hear important sounds in both ears

Your two Naída CI devices are able to share sound signals with each other. This means when one ear has a clear listening advantage, you can instantly send that better sound to the other device, so you hear the clearer sound in both ears.

Crystal clear wireless streaming

You can choose from a wide selection of Phonak wireless accessories that stream audio directly to both sound processors for effortless hearing.

If bilateral implantation isn't right for you:

If you plan to hear with a cochlear implant in only one ear but do not have any hearing in your other ear, you can use a Naída Link CROS to send sounds from that side to your Naída CI so that you can enjoy hearing your best in quiet and noise without having to reposition yourself.3

Naída Link CROS

Hear From Wherever You Want

Born from Phonak CROS technology that has been proven with thousands of hearing aid users worldwide, the Naída Link CROS makes it easier to walk into any listening situation with confidence.3

Not only do you benefit from hearing sound from both sides, the Naída CI and Naída Link CROS microphones simultaneously and automatically adapt to different environments so that you hear better in quiet and in noise.*4

Hearing with one ear makes it even more challenging to hear in noisy conditions. But with the Naída Link CROS solution you can take advantage of the two microphones on each ear to help you focus on the person in front of you and not the unwanted sounds around you.

*Compared to Naída CI alone

“ I no longer have to strain to hear in a noisy restaurant. I can sit anywhere at the table and enjoy the conversation.”
Jill K., AB Recipient

Simply switch it on and enjoy hearing from both sides

With the Naída Link CROS, you just wear it and go. There is no need to adjust anything. It automatically adapts to your hearing needs as you go through your day. You can wear it all day. It’s really so simple you’ll forget you’re wearing it.

Almost Invisible, you can wear it without it being noticed.

With no wires to weigh you down, the Naída Link CROS is the perfect companion for your Naída CI and makes it simple to hear more.
