Hear More Clearly With a BiCROS Hearing Aid: What You Need to Know
Hearing clearly can become challenging when one ear has little or no usable hearing while the other ear retains some hearing ability. In these situations, traditional hearing aids may not provide the right solution. A BiCROS hearing aid is designed specifically for people who have significant or profound hearing loss in one ear and hearing loss in the better ear that can benefit from amplification.
Rather than simply amplifying sound in both ears, a BiCROS system captures sound arriving on the poorer-hearing side and wirelessly sends it to a hearing aid worn on the better-hearing ear. This can make conversations and everyday sounds easier to access, particularly when someone is speaking from the side with poorer hearing.
Understanding how this technology works, who it is suitable for, and what features to consider can help you make a more informed decision about your hearing care.
What Is a BiCROS Hearing Aid?
A BiCROS hearing aid is a specialised hearing system for people who have little or no functional hearing in one ear and hearing loss in the other ear.
BiCROS stands for Bilateral Contralateral Routing of Signal. The system generally uses two devices:
- A microphone/transmitter on the poorer-hearing side picks up surrounding sounds.
- The signal is wirelessly transmitted to the hearing aid on the better-hearing side.
- The hearing aid amplifies the sound according to the hearing needs of the better ear.
- Sounds from both sides can therefore be presented to the better-hearing ear.
This differs from a CROS hearing aid, which is typically intended for someone with unaidable hearing loss in one ear but normal or near-normal hearing in the other.
How Does a BiCROS Hearing Aid Work?
The main purpose of a BiCROS hearing aid is to help overcome the difficulty of hearing sounds that originate on the side of the poorer ear.
Imagine sitting at a restaurant with your better-hearing ear facing your companion. If another person speaks from your opposite side, their voice may be difficult to detect. The BiCROS transmitter can pick up that speech and send the audio to the hearing aid on your better-hearing side.
Modern systems can use digital signal processing to manage incoming sounds and provide appropriate amplification. Depending on the model, additional technologies may help with background noise, feedback management and listening comfort.
It is important to remember that a BiCROS system does not restore normal hearing to the poorer ear. Instead, it provides a way for sounds arriving from that side to reach the better-hearing ear.
Who Can Benefit From a BiCROS Hearing Aid?
A BiCROS hearing aid may be considered when there is a significant difference in hearing between the two ears.
It can be particularly relevant for someone who has:
- Little or no usable hearing in one ear.
- Hearing loss in the opposite ear that requires amplification.
- Difficulty hearing people who speak from the side of the poorer-hearing ear.
- Challenges following conversations in group environments.
- Difficulty detecting sounds coming from different directions.
An appropriate hearing assessment is essential before choosing a BiCROS system. Hearing professionals can evaluate hearing levels in both ears and determine whether CROS, BiCROS, conventional hearing aids or another solution is more appropriate.
BiCROS Hearing Aid vs Traditional Hearing Aids
Traditional hearing aids are designed to amplify sound for an ear that has sufficient residual hearing to benefit from amplification. When one ear has little or no usable hearing, simply placing a conventional hearing aid on that side may not provide useful results.
A BiCROS system approaches the situation differently. It transfers sound detected on the poorer-hearing side to the better-hearing ear, while also providing amplification for that better ear when necessary.
The difference can be summarised simply:
Traditional hearing aids: amplify sound for ears that can benefit from amplification.
CROS: transfers sound from an unaidable ear to an ear with normal or near-normal hearing.
BiCROS: transfers sound from an unaidable ear to an ear that also needs amplification.
The right choice depends on the individual's hearing test results, lifestyle and listening needs.
Key Features to Look For in a BiCROS Hearing Aid
Technology varies between hearing aid models, so it is worth discussing available features with a hearing professional.
Wireless Connectivity
Wireless connectivity can make everyday listening more convenient. Some hearing devices can connect with smartphones and compatible electronics, allowing users to stream calls, music or other audio.
If connectivity is important to you, you may also want to explore Bluetooth in ear hearing aids and ask which options are compatible with your phone.
Background Noise Management
Restaurants, family gatherings and busy public spaces can be difficult listening environments. Digital noise management and directional microphone technologies may help make speech more comfortable to follow, depending on the device and surroundings.
Comfortable, Discreet Design
Because hearing aids are worn throughout the day, comfort and fit matter. Some users prefer smaller, less noticeable devices.
Those exploring discreet hearing solutions can learn more about options such as the best invisible hearing aid and discuss whether an invisible style is appropriate for their hearing requirements.
Rechargeable Options
Rechargeable hearing aids can be convenient for people who do not want to regularly replace disposable batteries. Charging requirements vary by device, so ask about expected battery life and charging options before making a decision.
What Are the Benefits of a BiCROS Hearing Aid?
One of the biggest advantages of a BiCROS hearing aid is improved awareness of sound coming from the side with little or no usable hearing.
Potential benefits include:
- Better access to conversations from the poorer-hearing side.
- Greater awareness of sounds around you.
- Easier communication in certain group situations.
- Improved access to speech when someone approaches from the unaidable side.
- Personalised amplification for the better-hearing ear.
However, expectations are important. A BiCROS system does not create true hearing in the poorer ear and may not completely restore the ability to determine where every sound originates.
Getting Used to a BiCROS Hearing Aid
Like other hearing technology, a BiCROS system may take time to get used to. Your brain needs to adapt to receiving sounds from the poorer-hearing side through the better ear.
During the adjustment period, some sounds may initially seem unfamiliar or unusually noticeable. Wearing the devices consistently, following professional recommendations and attending follow-up appointments can help with the adaptation process.
Your hearing professional may also fine-tune the settings based on your experiences in different environments.
Choosing the Right Hearing Care Provider
Selecting the right hearing care provider is an important part of the process. A hearing assessment should look at both ears and consider how your hearing affects communication in real-world situations.
A professional can discuss your hearing results, lifestyle, technology preferences and budget before recommending an appropriate option.

Frequently Asked Questions About BiCROS Hearing Aids
Can a BiCROS hearing aid improve hearing in the poorer ear?
No. A BiCROS system does not restore hearing in an ear with little or no usable hearing. Instead, it transfers sounds from that side to the better-hearing ear.
Is a BiCROS hearing aid the same as a CROS hearing aid?
No. CROS systems generally transfer sound to an ear with normal or near-normal hearing, while BiCROS systems transfer sound to an ear that also requires amplification.
Can I use Bluetooth with a BiCROS system?
Some modern hearing systems offer Bluetooth or other wireless connectivity. Compatibility depends on the specific hearing aid and smartphone or device.
How do I know whether BiCROS is right for me?
A comprehensive hearing assessment is the best starting point. Your hearing professional can determine whether BiCROS, CROS, conventional hearing aids or another hearing solution better matches your hearing profile.
Conclusion: Is a BiCROS Hearing Aid Right for You?
A BiCROS hearing aid can be a valuable hearing solution for people with significant hearing loss in one ear and hearing loss in the other ear that requires amplification. By capturing sound from the poorer-hearing side and transferring it to the better-hearing ear, the technology can make it easier to stay aware of conversations and sounds around you.
The best solution depends on your individual hearing test results, lifestyle, listening environments and personal preferences. A professional assessment can help you understand your options and set realistic expectations. If you are considering a BiCROS system, speak with a qualified hearing care professional to find out whether it could meet your everyday hearing needs.
