Ezairo 7150 SL, a wireless-enabled audio processor
From: ECN - 10/21/2015

Ezairo 7150 SL uses the ON Semiconductor's widely-implemented proprietary
digital signal processing (DSP) technology and brings wireless connectivity
to hearing aids and cochlear implants. The company has provided a complete
reference design of a behind-the-ear (BTE) hearing aid. The reference design
includes software, hardware, and firmware which enable advanced wireless
features. The control over BLE (CoBLE) function allows hearing aid users to
control an array of parameters from their smartphone. The user can adjust the
hearing aid’s volume, make program changes, check the battery status, and
receive phone alerts (such as incoming calls or text messages). It also
features a valuable ‘Find Me’ function to help users quickly locate a
misplaced hearing aid. The stereo audio streaming proprietary protocol
enables music to be streamed from any external audio source (smartphones,
tablet computers, televisions, etc.) through a remote dongle. The
connectivity range can reach up to 10 meters in good surrounding conditions.
