Your iPhone now has its own hearing aid. The ReSound LiNX is a smart hearing aid that provides you with direct sound streaming and a personalized experience. It has a small, slim design and lets you hear and understand things better. It pairs with your iPhone, iPad, and iPod Touch to bring you a higher quality hearing experience. LiNX essentially acts like a pair of wireless stereo headphones.
All sounds in ReSound LiNX are enhanced by Surround Sound by ReSound. The companion app for this system lets you fine tune it and customize its settings. It is location-aware, so you can switch to a pre-defined program automatically based on your location. What’s neat is you can find your lost LiNX using your iPhone.
