Signia CROS/BICROS Pure 312 AX Transmitter

About CROS/BICROS Pure 312 AX Transmitter

The Signia CROS/BiCROS Pure 312 AX Transmitter is designed specifically for people who have little to no usable hearing in one ear — a condition called single-sided deafness — or whose hearing loss is significantly different between the two ears. The transmitter sits behind your poorer ear in a slim RIC (Receiver-in-Canal) form factor and wirelessly captures sound from that side, sending it across to a compatible Signia hearing aid worn on your better ear. The result is that you stop missing conversations happening on your weaker side, whether that is someone speaking from the passenger seat of your car or a colleague addressing you from across a meeting table. In terms of sound quality, the Pure 312 AX transmitter is built on Signia's Augmented Xperience (AX) platform, which uses a split-processing approach: it handles speech and background noise on separate processors before blending them together. In practice, this means voices remain clearer even in noisy environments like a busy restaurant or a crowded market, rather than being drowned out by the surrounding din. The wireless transmission between the CROS transmitter and your receiver aid is designed to be seamless, with minimal delay, so you do not experience an unnatural lag when sound reaches you. The 312 battery format means you get a straightforward zinc-air disposable battery that is widely available across India, including at all HearClear clinics. Battery life will vary based on streaming usage, but the 312 cell is a reliable, easy-to-replace option that many users already feel comfortable managing. The transmitter connects via Signia's own wireless system, and when paired with a compatible Signia BiCROS hearing aid, you can also expect Bluetooth connectivity features from the aid side for streaming calls or audio from your smartphone. The device sits discreetly behind your ear, and because it uses a RIC housing, it is relatively lightweight and unobtrusive for daily wear. The microphone on the transmitter picks up sound naturally from your non-hearing side, so you do not need to consciously angle your head or ask people to always speak into your better ear. This product is not suitable for people with bilateral hearing loss of a similar degree in both ears — in that case, a standard pair of hearing aids would serve you better. It also requires a compatible Signia receiver aid to function; the transmitter alone will not amplify sound. If you are unsure whether you have single-sided deafness or asymmetric loss, the best starting point is a proper audiological evaluation. At ₹29,490, the CROS Pure 312 AX Transmitter is the transmitter component of a system, so factor in the cost of the companion receiver aid when budgeting.
