CROS and BiCROS hearing aids dramatically improve the quality of life for individuals with single-sided deafness or asymmetrical hearing loss. By restoring the ability to hear sounds from all directions, these systems enhance communication, reduce listening effort, and improve spatial awareness. Users often report feeling more confident and engaged in social, work, and recreational activities, making these devices invaluable for everyday life.

General Features
CROS (Contralateral Routing of Signals) and BiCROS (Bilateral Contralateral Routing of Signals) hearing aids are specialized solutions designed for individuals with single-sided deafness or asymmetrical hearing loss. A CROS system captures sound from the non-hearing ear and transmits it wirelessly to the hearing ear, ensuring the user can detect sounds from all directions. BiCROS devices add amplification for the hearing ear if it has hearing loss, enabling users to hear more clearly from both sides.
Technology
CROS and BiCROS hearing aids utilize wireless transmission technology to transfer sound from the non-hearing side to the hearing ear. Advanced models include features such as noise reduction, directional microphones, and feedback suppression to enhance speech clarity and reduce background noise. Many devices are equipped with Bluetooth connectivity, allowing users to stream audio from phones, TVs, and other devices directly to the hearing aid.
Age Suitability
CROS and BiCROS systems are suitable for adults and older children with single-sided deafness or asymmetric hearing loss. These devices are particularly beneficial for individuals who struggle with sound localization or understanding speech in noisy environments. However, younger children may find these devices challenging to adapt to, and alternative solutions may be more appropriate for early hearing interventions.
Design
CROS and BiCROS hearing aids are typically designed as behind-the-ear (BTE) or receiver-in-canal (RIC) models, making them discreet and comfortable to wear. The device on the non-hearing ear houses a microphone that captures sound and transmits it to the hearing ear. The hearing aid on the better-hearing ear processes and amplifies the sound as needed. These systems are lightweight and available in various styles to suit user preferences.
Suitability for Hearing Loss Types
CROS hearing aids are ideal for individuals with normal hearing in one ear and no usable hearing in the other. BiCROS systems are suited for those who have some degree of hearing loss in their better ear, requiring amplification in addition to sound routing. Both systems address the challenges of single-sided deafness by restoring a sense of balance in hearing.
Durability & Longevity
CROS and BiCROS hearing aids are built to withstand everyday wear and tear. High-quality materials and water-resistant designs ensure they remain functional in various conditions. With proper maintenance, these devices can last for several years. The wireless transmission components are engineered for durability, providing reliable performance over time.
Maintenance
Like all hearing aids, CROS and BiCROS systems require regular cleaning and care. The microphones and receivers should be kept free of debris to ensure clear sound transmission. Batteries or rechargeable units need to be maintained to avoid interruptions in performance. Periodic check-ups with an audiologist are recommended to adjust settings and address any issues that arise.
Customization & Flexibility
CROS and BiCROS systems offer extensive customization to meet individual needs. Audiologists can program the devices to optimize sound processing based on the user’s hearing profile and listening environments. Many models allow users to switch between multiple listening modes via a smartphone app or manual controls, providing flexibility in different situations such as conversations, crowded spaces, or outdoor settings.
Rechargeable Options
Modern CROS and BiCROS hearing aids often include rechargeable battery options, which are both environmentally friendly and convenient. Rechargeable models eliminate the need for frequent battery changes, making them ideal for users with dexterity challenges. Charging docks are typically included, offering a full day of use with overnight charging.
