Lumity
Developed for users with hearing loss that cannot be supported in one ear, the Lumity-based CROS hearing solution supports access to sounds coming from both sides.

Lumity Platform: Prioritizing Speech Understanding
The CROS Lumity brings the speech-focused sound processing approach of the Lumity platform to users with unilateral hearing loss. It aims to support environmental awareness by providing access to sound environments on both sides.
Don't Miss Sounds from the Non-Hearing Side
The CROS system detects sounds from the side with unsupported hearing loss and transmits them to your better-hearing ear's compatible hearing device. This can reduce communication difficulties depending on which side the speaker is on.
Non-Hearing Side
The CROS microphone detects speech and environmental sounds on this side.
Better Hearing Side
Sound information is transmitted wirelessly to the compatible Lumity hearing device.
CROS Transmission
Supports access to sounds from the non-hearing side through the better-hearing ear.
StereoZoom
A technology that supports focusing more effectively on the target speech in the compatible device system.
SpeechSensor
Supports microphone behavior by analyzing the direction of speech.
myPhonak
An app support that helps manage the personal settings of the compatible system.
Wider Access to Sounds in Your Environment
One of the biggest challenges in unilateral hearing loss is missing conversations and environmental sounds occurring on the side with hearing loss. CROS Lumity aims to enhance environmental awareness by supporting access to sound information from both sides.

For Those with Unilateral Hearing Loss
CROS Lumity is evaluated for users who do not obtain sufficient benefit from a hearing aid in one ear, while having better hearing in the other ear. The performance of both ears in hearing and speech discrimination should be examined together to determine the appropriate CROS system.

Regularly Maintain Both Sides of the CROS System
It is recommended to clean your CROS device and paired hearing device daily with a dry cloth, and to keep the speaker and charging contacts clean.
Keeping the myPhonak app updated and attending regular check-up appointments supports the optimization of the system according to your needs.
