Microphone & Receiver in-ear (M&RIE)

The key new feature of this revolutionary hearing aid is the incorporation of a 3rd microphone on ear hearing aid – located on the end of the speaker wire that sits in the ear. See video.

The new microphone makes much better use of the natural shape of the ear to funnel and amplify important speech cues much like nature does for normal hearing people. This microphone works in an all-around focus at lower background noise levels. When background noise increase the two microphones in the hearing aid body take over and can give much better directional focus (directional microphones are the proven best technology in hearing aids, excluding accessories, for improving speech in noise).

The disadvantage of M&RIE is that the microphone in the ear can block more easily and requires more maintenance – the microphone does have replaceable microphone guards, but they are very fiddly to change.

Another disadvantage is greater risk of feedback with the microphone being closer to the speaker – ReSound have improved their feedback suppression technology but there are limits and this means more severe ‘ski-slope’ losses may lead to increased feedback whistle.

Binaural Beam Forming & Ultra Focus

ReSound ONE incorporates new technology that allows all 4 of the ‘directional’ microphones on top of the two hearing aids to communicate with each other (inter-ear).

This gives us ‘binaural beamforming‘ – and an improvement in speech recognition in noise (under simple laboratory conditions) has been reported to be higher than what is typical with independently operating directional hearing aids.

Binaural beamforming has been designed to balance maximising speech in noise to the front whilst preserving spatial hearing cues for localisation of sounds all around.  Giving great performance and natural sound results.

Ultra Focus

Ultra Focus is a new quick access feature within the app that gives maximum focus and clarity for speech in loud noise where the speaker is in front.

State of the art battery charging technology

Using lithium-ion batteries which do not drain over the course of their life (2 years)


  • 30 hours standard use with 3 hours full charge
  • 16 hours use with 1 hour charge
  • 8 hours use with 30 minute charge
  • 4 years full performance

Usage times will be reduced if streaming audio – i.e. 25 hours on a full charge if streaming 100% of the time. Usage times will reduce gradually but performance will not.

The premium (larger) charging unit can give a further 5 days of portable charging (if fully charged) – ideal for short trips away.

After 4 years it is advised to get the battery changed (we offer 5 year warranty).

PLEASE NOTE – The hearing aids come with one charger of your choice as per our price list.
