About CROS/BICROS Pure C&G AX Transmitter
The Signia CROS/BiCROS Pure C&G AX Transmitter is designed specifically for people who have no usable hearing in one ear — a condition called single-sided deafness (SSD) — or who have significantly poorer hearing on one side compared to the other. Rather than amplifying sound directly, this slim RIC-style transmitter picks up sounds from your poorer or non-hearing ear and wirelessly streams them across to a companion hearing aid worn on your better ear. The result is that you stop missing conversations, traffic, or voices that originate from your 'bad' side, without the discomfort of a device that tries to amplify a side that cannot benefit from amplification. In terms of sound quality, the Pure C&G AX sits on Signia's AX (Augmented Xperience) platform, which processes foreground speech and background sound on separate, parallel processors before blending them. In practice, this means voices directed at you from your non-hearing side arrive at your better ear with clarity rather than as a muddled stream. Users who work in offices, attend family gatherings, or ride in cars frequently report the biggest day-to-day benefit, because those are exactly the situations where sound direction matters most. The transmitter itself is built in a discreet RIC form factor, so it sits behind your ear with a thin wire running to the ear canal — far less conspicuous than older CROS designs. It pairs wirelessly with a compatible Signia AX receiver aid on the opposite ear, and the two communicate in real time so that the sound handoff feels natural rather than delayed or artificial. Bluetooth connectivity lets you stream calls and audio from Android and iOS smartphones directly, and Signia's own app gives you manual control over volume and programmes if you prefer not to rely solely on the automatic settings. Battery life on the standard version runs through a full day of typical use, and a rechargeable variant is available if you prefer not to manage disposable cells. The device is rated for everyday moisture and dust exposure, which matters if you live in a humid city or are physically active. This transmitter is not a standalone hearing aid and will not help you if you have usable residual hearing in both ears — in that case, a conventional pair of hearing aids or a single-ear amplification device would serve you better. It also requires a matched Signia AX receiver aid on your better ear; it cannot be paired with devices from other brands or older Signia platforms. If your hearing loss profile does not include single-sided or highly asymmetric loss, a Signia audiologist will almost certainly recommend a different product after your assessment. At ₹35,990, the CROS Pure C&G AX Transmitter is priced for the receiver-side aid to be purchased separately, so factor in the total system cost when budgeting. HearClear India stocks this device across its 41+ clinics and offers a free hearing test so you can confirm whether a CROS or BiCROS system genuinely matches your hearing profile before you commit.

Who this is for
- Best for adults with complete single-sided deafness who miss sounds and speech originating from their non-hearing side.
- Best for people with significantly asymmetric hearing loss (BiCROS) who need both crossover transmission and amplification on the better ear.
- Best for professionals and students who need to follow conversations in meetings or classrooms where speakers move around them.
- Best for active users who want a discreet RIC-style CROS device with smartphone streaming built in.
How it compares
- vs a conventional RIC hearing aid: a conventional RIC amplifies sound at the ear it is worn on, while this transmitter captures sound from a non-functional ear and relays it — two fundamentally different solutions for different types of loss.
- vs a bone-anchored hearing system (BAHA): a BAHA uses bone conduction and typically involves a surgical implant or external abutment, whereas the CROS Pure C&G AX is fully non-surgical and non-invasive.
- vs older analogue CROS systems: the AX platform offers digital dual-processing of speech and background sound and wireless smartphone connectivity that older wired or analogue CROS designs do not provide.
Frequently asked questions
What is the difference between a CROS and a BiCROS fitting?
A CROS fitting is for people with no usable hearing in one ear and normal hearing in the other — the transmitter sends sound to an unamplifed receiver. A BiCROS fitting is for people who have no usable hearing in one ear but also have hearing loss in the better ear — the receiver side also amplifies incoming sound. Your audiologist will confirm which configuration suits you after a hearing test.
Does this device work as a standalone hearing aid?
No. The CROS Pure C&G AX Transmitter only captures and wirelessly sends sound from your poorer ear; it does not amplify sound on its own. It must be paired with a compatible Signia AX receiver hearing aid worn on your better ear to function.
Can I connect this system to my smartphone?
Yes. The system supports Bluetooth streaming for calls and audio from both Android and iOS devices. You can also use the Signia app to adjust volume and switch listening programmes directly from your phone.
Is the transmitter rechargeable?
A rechargeable version is available. If you prefer disposable batteries, a standard battery-powered variant is also offered. Ask your HearClear audiologist which option suits your daily routine before purchasing.
Will there be a noticeable delay when sound crosses from the transmitter to the receiver aid?
The AX platform is designed to minimise latency so that the crossover feels natural during conversation. Most users do not report a perceptible delay in everyday listening situations, though individual experience can vary.
What is the total cost of a complete CROS AX system?
The transmitter is priced at ₹35,990, but you also need a compatible Signia AX receiver hearing aid for the better ear, which is sold separately. The combined system cost will depend on the receiver model you choose. A HearClear audiologist can give you a full quote after your free hearing test.
