The Rexton BiCore R 312 is a Receiver-In-Canal (RIC) hearing aid designed for natural, high-quality sound with extended battery life. It is powered by a user-replaceable 312 button-cell battery, delivering up to 89 hours of use per battery without streaming, or up to 72 hours with 20 hours of daily audio streaming.

Powered by Rexton's BiCore Multi-track Technology®, the device removes unwanted background noise while emphasizing speech sounds, making conversations easier to follow even in crowded or noisy environments. An ultra-quick binaural link keeps left and right hearing aids synchronized when worn as a pair, reacting instantly and precisely to changes in the surrounding sound environment.

The BiCore R 312 supports direct audio streaming from both iOS and Android smartphones for hands-free phone calls, music, and media. It carries ATEX certification, confirming it is intrinsically safe for use in potentially explosive environments such as paint and chemical manufacturing facilities, petrol stations, and flour mills. The device is also CROS compatible for users with single-sided hearing loss.

Built to Rexton's Lifeproof™ durability standards, it is rigorously tested against drops, rain, vibration, and UV exposure to ensure reliable daily performance. Available in 10 color options, this single-unit listing allows one hearing aid to be purchased independently. Sold exclusively through Costco Hearing Aid Centers, which include free follow-up appointments, a 180-day return policy, and a two-year loss and damage warranty.
