Equipped with our primax™ star platform, the new Pure® 13 BT primax revolutionizes precise hearing. It combines the industry’s most innovative application of Bluetooth® low energy with high-definition binaural hearing to deliver better-than-normal* hearing and a direct connection to iPhone®. It’s the world’s first hearing aid to offer audiological benefit through Bluetooth®. It uses detailed, Bluetooth-based data in combination with the new myControl™ App to provide a clear overview of the wearer’s acoustic environment.

For example, if you’re walking in a noisy environment, the hearing aids register that you are in motion, and automatically adjust to better hear a conversation partner at your side or from the back while maintaining awareness of environmental sounds like sirens, approaching vehicles, or pedestrians. This improves both listening comfort and safety.

More on Pure 13 BT primax and the myControl App.

In combination with the myControl App, the Pure 13 BT provides better than normal hearing* tailored to your individual lifestyle. The app does more than enable direct streaming, it also sends information about your surroundings to your hearing aids for the best possible hearing while on the move — for relaxation and safety no matter what comes your way.

* Two independent clinical studies have shown that binax can even exceed normal hearing in certain challenging hearing situations (University of Northern Colorado, 2014; Oldenburg Hearing Center, 2013): Speech Reception Thresholds (SRT) in cocktail-party situations improved up to 2.9 dB for wearers with mild to moderate hearing loss using Carat binax or Pure binax hearing aids with narrow directionality, compared to people with normal hearing.


World’s first use of iPhone motion sensors.

People frequently move while they are speaking, so hearing aids should react dynamically and adjust to changing listening situations. Up until now, this data was missing, but with the new myControl App, it’s finally available.

The app uses Bluetooth technology to provide detailed data on your acoustic environment. Even in a vehicle, Pure 13 BT enables enjoyment of the best possible listening experience and focus on what’s important to hear.
