ReSound ONE™ with M&RIE (Microphone & Receiver-In-Ear) introduces a new class of hearing aids* with a microphone and receiver positioned inside the ear, so patients can collect the whole sound environment just as nature intended. M&RIE offers the most natural sound quality by having a third microphone in the tragal area of the ear. This allows for the most natural and reproducible sound of the hearing aid to the ear canal. 

This technology improvement is called All Access Directionality. It is a feature that allows the user to have greater hearing in any environment in which they find themselves. It allows for the hearing aid to seek the speech and reduce the noise by having the microphones detect nuances of speech and directionality of the sound. 

Additionally, an enhanced feature called Ultra Focus is a feature that provides the best one-to-one hearing experience. It allows the hearing aid user to narrow down the directionality of the hearing aid to be front focused and improve the signal to noise ratio of the sound with ultra focus to the front.
