Resound ONE Technology

The Resound One introduces M&RIE (Microphone and Receiver in the Ear) technology. M&RIE places an additional (3rd) microphone discreetly inside the ear canal. Typically 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-ear microphone collects sound inside the ear canal. It uses the unique shape of the outer ear for a more individualised and natural hearing sound experience.


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



Ultra Focus uses all six microphones of the hearing aids to focus on the speech in front of the patient while ignoring sound from the sides. The user can easily activate it and aims to prioritise one on one addresses in the noisiest environments.







Resound ONE Chargers


Resound One has an improved rechargeable battery with up to 30 hours of battery life or 25 hours with unlimited streaming. Two charging cases are available. One with a built-in battery allows up to three charges on the go, and a smaller one without a battery needs to be plugged into work.

ReSound ONE App

With ReSound ONE, you can connect directly to your iPhone or Android (version 10 and above) smartphone and the world around you and stream audio and wireless calls to your ears via the stable Bluetooth – Low Energy.

Resound Wireless Accessories

ReSound have a range of wireless accessories to expand and improve your hearing experience.  They are compatible with most ReSound aids. All of them are effective and simple to set up and use.


ReSound 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 lets you stream calls and music directly 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 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 comfortable volume‚ while you stream sound to your aids at your preferred level.








For those without the ReSound Smartphone 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 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.
