For people who can only hear on one side, listening can be extremely strenuous in many daily situations. Understanding speech is particularly difficult in noisy surroundings and can be very exhausting. Signia CROS or BiCROS hearing aids now offer an innovative solution for people with an hearing loss in one ear. Wireless technology helps them hear and understand every word again. In addition, it significantly reduces their listening effort.

People with a unilateral un-aidable hearing loss are particularly challenged. Whether on the street, in the office, or talking with friends, sounds and voices are indistinct or not heard at all when they come from the “wrong” side. Constantly moving your head to try to hear better is strenuous and also not always an option, for example when driving. Above all, the ability to understand speech is severely limited. The Signia CROS devices wirelessly transmit the signals from the ear with hearing loss to the other ear can help.

Hearing sounds from both sides

With the new Signia CROS or BiCROS solutions, people with un-aidable hearing loss in one ear can hear every word, even when the person speaking is standing on the “wrong side”. The new solutions offer even more benefits to people with unilaterally un-aidable hearing loss. They are light and discreet, and operate with high energy efficiency.


The Signia CROS transmitter on the unaidable ear picks up the sound and wirelessly transmits the processed signals to a Signia hearing aid on the other ear to be heard. If this other ear can hear normally, this is referred to as a CROS solution.

If the patient is affected by unaidable hearing on one side, and impaired hearing on the other, the Signia CROS transmitter is worn on the unaidable side and is able to wirelessly transmit any sound picked up to the hearing aid worn on the impaired side. The hearing aid upon receiving the signal mixes it with its own input and amplifies the mixed signal. This solution is called BiCROS.
