ReSound Key 4 Hearing Aid


ReSound Key is the new complete hearing aid collection in the essential category. ReSound Key hearing aids are designed to work comfortably and reliably with your own ears based on the Organic Hearing philosophy. The technology works to emulate the natural hearing experience as closely as possible. They give you the confidence and guidance to grow with your experiences and hear your best every day.

Hearing sounds clearly with less effort: ReSound Key leverages Natural Directionality II to support better listening in noise by enabling both ears to work together. It gives you a focused response in one ear while enabling them to monitor the environment with the other ear.

Streaming great sound from the smart devices: The unmatched connectivity of ReSound Kay connects you to phones and tablets so you can communicate your way. You can connect directly to your iPhone or Android™ smartphone and the world around you, and stream audio and wireless calls to your ears via the stable Bluetooth® Low Energy.

ReSound Assist and ReSound Assist Live: Convenient remote and real-time support from the comfort and safety of your own home. Now, you don’t have to worry about going out with all the hassle.

SoundLife Hearing provides professional consultation and can help you to restore your hearing. While you’re at it, grab this opportunity and get the 7 days Hearing Aid Home Trial Program. Better be quick, it is available for limited slots only. (T&C applied)
