ReSound One RIC Microphones

The ReSound One introduces M&RIE (Microphone and Receiver in the Ear) technology to the market. M&RIE places an additional (3rd) microphone discreetly placed inside the ear canal. Normally with Receiver in the canal technology you have the speaker (receiver) in the ear canal and the microphones on the hearing device above the ear. This 3rd in the ear microphone is responsible for collecting sound right inside the ear canal and uses the unique shape of the outer ear for a more individualized and natural hearing sound experience.


All Access Directionality – Automatically adjusts how the microphones operate depending on the listening environment.



Ultra Focus uses all 6 microphones of the hearing aids to focus on the speech in front of the patient while ignoring sound from the sides. It can be easily activated by the user and aims to prioritise 1 on 1 speech in the noisiest environments.









Resound One has improved rechargeable battery with up to 30 hours of battery life or 25 hours with unlimited streaming. Two charging cases are available.

ReSound Multi Mic

Multi Mic is a small microphone that allows you to hear up to 25 meters away.  The microphone can be worn by the person you want to hear, or, the microphone can be placed on the table in a group of people.  The sound is streamed direct to the hearing aids and you will hear well even in heavy background noise.  The Multi Mic also connects to loop and FM systems (FM receiver required) and has an input socket for streaming audio from any device with a headphones output.





ReSound Phone Clip +

ReSound Phone Clip allows you to stream calls and music direct to your hearing aids from any Bluetooth enabled phone. This provides better audibility of phone calls even in noisy environments.  Effectively, the Phone Clip + gives you high quality, hands-free calls.









ReSound TV Streamer 2

ReSound TV Streamer 2 streams stereo sound directly from your TV, computer, tablet, radio, or stereo system to your hearing aids.  Effectively, this accessory transforms your hearing aids into wireless headphones – giving you independent volume adjustment and clear sound up to 7 meters away.   The ReSound TV Streamer 2 allows your friends and family to listen at their own comfortable volume – while you stream sound to your aids at your preferred level.








ReSound Remote Control

For those without the ReSound Smart phone App, a separate ReSound Remote Control allows you to adjust the volume of your aids, switch programs and mute the aids.  The control can connect the aids to both the ReSound Multi Mic and the ReSound TV Streamer 2 and adjust the sound when streaming.  Remote controls are favoured by hearing aid users who find using the button controls on their aids fiddly and wish to make adjustments discreetly.
