The Rexton Reach R-Li T is a premium receiver-in-canal (RIC) hearing aid available exclusively at Costco. This single-aid bundle is designed for individuals with unilateral hearing loss and includes one hearing aid plus a portable travel charger. The Reach R-Li T is the flagship model from Rexton, a brand belonging to Denmark's WS Audiology group and one of the pioneers of Costco's hearing aid program.

The Reach R-Li T delivers 48 processing channels and 20 adjustment bands, incorporating Rexton's Multi-Voice Focus technology to prioritize speech from different directions while suppressing background noise. It supports Bluetooth LE Audio and Auracast, enabling audio streaming for both iOS and Android devices and hands-free calling for iPhone users. The gyroscope and motion sensors allow for automatic scene detection. Additional features include Wind Noise Reduction, Echo Reduction, Feedback Suppression, Voice Stabilizer, and a telecoil for use in looped venues. The aid is IP68-rated, making it dustproof and waterproof to 2 meters for up to 30 minutes, and ATEX-certified for use in hazardous environments.

Battery life reaches up to 39 hours per charge (34 hours with 5 hours of streaming), with a full recharge taking 3 to 4 hours. The included travel charger provides up to 3 full charges without a power outlet. The hearing aid turns on automatically when removed from the charger and powers off when placed back in. It is available in rose gold, dark champagne, sand brown, and almost black. The Rexton App allows users to adjust volume, directional hearing, and sound balance directly from a smartphone.
