Wireless connectivity

Expand patients' worlds through sound

Wireless connectivity is shifting the boundaries of how people with hearing loss can access and enjoy sound, information, and entertainment. The ReSound 2.4 GHz wireless technology works seamlessly and intuitively, such as the direct streaming from iOS and Android* devices with no need for intermediate devices.

*Full streaming compatibility with Android devices requires minimum Android v10 and Bluetooth 5.0 and that functionality has been enabled by the phone manufacturer and service carrier. Although ReSound strives to achieve seamless device compatibilities, ReSound cannot guarantee full compatibility with all Android devices.


Advanced and intuitive, ReSound apps provide each patient with a personalized hearing experience, enabling them to easily and discreetly control hearing aid settings right from their phone.

I can honestly say in the last 5 years of practicing audiology I have never had patients react so positively towards the sound quality of a device on the day of their fitting. It is really nice to hear these comments and how satisfied people are.
