Phonak CROS Lumity

Solution for Single-Sided Hearing Loss (SSD)

The Phonak CROS Lumity is a specialized hearing solution designed for people who have hearing loss in one ear and normal or better hearing in the other ear. Instead of amplifying sound in the weak ear, it captures sound from that side and wirelessly sends it to the better ear, giving a complete 360° listening experience.

It works together with a compatible Phonak Lumity hearing aid (like Audéo Lumity, Naída Lumity, or Sky Lumity) to deliver clear, natural sound from all directions.  

Phonak CROS Lumity offers CROS and BiCROS solutions, for those with unaidable hearing loss in one ear and normal hearing or aidable hearing loss in the other ear.

- Compatible with Audéo™ L-R/RT, Naída™ L-PR & Sky™ L-PR
- Phonak SmartSpeech™ Technology with StereoZoom 2.0 Speech intelligibility
- Universal connectivity to Bluetooth® enabled devices
- Personalization with the myPhonak app

 How It Works

The system uses two parts:

• A CROS device on the poorer ear picks up sound
• A compatible Lumity hearing aid on the better ear receives and plays the sound

This allows the brain to receive sound from both sides, improving awareness and communication naturally.  

Why Choose CROS Lumity?

The CROS Lumity system is built to restore balance in hearing by solving the biggest challenge of single-sided hearing loss—missing sound from one direction. It gives a more natural listening experience, reduces strain in conversations, and helps users feel more connected in daily life.
