Siemen’s easyTek hearing aids

Siemen’s showed off their easyTek hearing aid system at the CES 2015 show this month, where one can change the directivity of the hearing aid microphones using the easyTek smartphone app for Apple iphones or Android devices. The plastic disk shown in the image connects the hearing aid to a bluetooth device such as a phone, MP3 player, TV etc, and permits the audio from the media player to be fed directly to the hearing aid.
