Hearing loss in one ear can make everyday conversations, phone calls, and understanding speech in noisy environments challenging. Fortunately, modern hearing technology offers solutions designed to help people hear sounds coming from their weaker ear. CROS hearing aids and BiCROS hearing aids are two such options that can help people with single-sided hearing loss hear more comfortably.
In this guide, we explain how these devices work, their key differences, who may benefit from them, and how RK Hear Care can help you explore the right hearing solution.
What Are CROS Hearing Aids?
CROS stands for Contralateral Routing of Signal. CROS hearing aids are designed for people who have little or no usable hearing in one ear but have normal or near-normal hearing in the other ear.
The system typically consists of a microphone worn on the ear with poorer hearing and a receiving device worn on the better-hearing ear. The microphone captures sounds from the weaker side and wirelessly transmits them to the better ear.
For example, if someone speaks to you from your left side and your left ear has profound hearing loss, a CROS system can send that sound to your right ear, making it easier to hear the speaker.
Benefits of CROS Hearing Aids
- Help you hear sounds coming from your poorer-hearing side.
- Improve awareness of conversations when speakers are positioned to one side.
- Reduce the need to constantly turn your head toward sounds.
- Support communication in everyday social and work situations.
CROS hearing aids do not restore hearing in the affected ear or provide true binaural hearing. They route sound to the better ear, and their effectiveness depends on the listening environment.
What Are BiCROS Hearing Aids?
BiCROS stands for Bilateral Contralateral Routing of Signal. These devices are intended for people who have significant hearing loss in one ear and some degree of hearing loss in the other ear.
Like a CROS system, a BiCROS system captures sounds from the poorer-hearing side and sends them to the better ear. However, the receiving device also amplifies sound for the better ear because that ear requires hearing assistance too.
For example, a person with severe hearing loss in the left ear and mild-to-moderate hearing loss in the right ear may benefit from a BiCROS system. It routes sound from the left side and amplifies incoming sound to suit the hearing needs of the right ear.
Benefits of BiCROS Hearing Aids
- Route sounds from the poorer-hearing side to the better ear.
- Amplify sounds to compensate for hearing loss in the receiving ear.
- Make conversations easier to follow in suitable listening environments.
- Offer a practical option for people with different levels of hearing loss in each ear.
CROS vs BiCROS Hearing Aids: What Is the Difference?
Understanding the difference between these two single-sided deafness devices is important when choosing a hearing solution.
| Feature | CROS Hearing Aids | BiCROS Hearing Aids |
|---|---|---|
| Hearing in the better ear | Normal or near-normal | Also affected by hearing loss |
| Sound routing | Yes | Yes |
| Amplification in the better ear | Generally not required | Required |
| Main purpose | Route sound from the poorer ear | Route sound and amplify the receiving ear |
| Suitable for | Single-sided deafness with a usable better ear | Asymmetric hearing loss affecting both ears |
The most suitable option depends on your hearing test results, listening needs, and personal preferences.
Who Can Benefit From CROS and BiCROS Hearing Aids?
CROS hearing aids may suit people with single-sided deafness who have normal or near-normal hearing in the other ear. BiCROS hearing aids may be appropriate when the better ear also has hearing loss requiring amplification.
These devices may be considered when hearing loss results from various causes, including certain inner-ear conditions, sudden hearing loss, or other medical problems. However, new or sudden hearing loss requires prompt medical assessment rather than simply purchasing a hearing aid.
An audiologist or hearing-care professional can evaluate your hearing and help determine whether a CROS or BiCROS system is appropriate.

Frequently Asked Questions
1. Are CROS hearing aids suitable for single-sided deafness?
Yes. CROS hearing aids are designed primarily for people with little or no usable hearing in one ear and normal or near-normal hearing in the other.
2. Can BiCROS hearing aids help if both ears have hearing loss?
They may help when one ear has significantly poorer hearing and the better ear also needs amplification. A professional hearing assessment is essential to determine suitability.
3. Do CROS hearing aids restore hearing in the deaf ear?
No. They transmit sound from the poorer-hearing side to the better ear rather than restoring hearing in the affected ear.
4. Which is better: CROS or BiCROS hearing aids?
Neither is universally better. CROS is generally intended for a person with a normal or near-normal better ear, while BiCROS is designed for someone who also needs amplification in that ear.
