The combination of system processing delays and external sounds leaking into the ear canal can create a comb-filtering effect, causing users to perceive echoes in the sound. This can ultimately make it difficult for users to adapt to the sound quality of hearing aids. Rehear, through exclusive circuit design and the assistance of AI, has reduced signal delays in Rehear mode to an industry-leading 0.2 ms. This significantly diminishes the comb-filtering effect, ensuring that the sound quality of the hearing aids remains as clear and bright as the original sound.
