Hearing aid receives stereo audio direct from iOS devices
From: Evaluation Engineering - 08/07/2014

The ReSound LiNX hearing aid can receive high-quality stereo audio direct
from iOS devices such as an iPhone, iPad, or iPod touch, without the need for
any other intermediary (typically pendant-like) remote or accessory, which
according to GN ReSound is a common drawback of traditional hearing aid
designs.

Users can also customize their hearing experience via the accompanying
ReSound Smart app that can be used, for instance, to set preferred volume
levels as well as treble and bass tone settings to produce the optimum
preferred audio reproduction and enhancement for each individual end user,
given that no two human ears (and brains) ever quite respond to audio
stimulus in exactly the same way.
