Rexton describes Reach Multi-Voice Focus as scanning around the wearer with four focus beams and adapting as speakers move or change. The manufacturer says the environment is analysed 1,000 times per second; that is a manufacturer claim rather than a guarantee of identical benefit for everyone.
BiCore takes a different established approach, processing speech and competing noise separately before bringing them together. Rexton's other clear point of difference is its rugged option for people who want greater resilience without making the misleading promise that a hearing aid is indestructible.
