(1) Voice clarifying technology(VCT):
(2) Noise cancelling technology(NCT):
(3) Automatic signal control(ASC):
Reduce background sound of TV, increase the sound of dialogues, so that hard to
hear words can easily stand out, making television dialogues easier to understand.
Reduce the environmental noise to help the users to focus on listening to the
dialogues of TV.
Hearing disable people's adaptive faculty for volume change is weak (can't hear
loud sound, and can't hear low volume sound), our circuit will adjust the sudden
change volume and make the output volume stable. It will avoid strong signal
hurting the users' listening.
Specially designed for hearing loss people whose right and left hearing levels
are different. Users can adjust the right & left volume to best fit themselves by
the VOLume and BALance.

(3) Regular and extensional hearing aid:
4) Hearing aid function for phone call:
(5) Computer chatting headphone with hearing aid function:
6) Wired headphone with hearing aid function:
The receiver can be used as a regular hearing aid. It's very convenient to use in
noisy environment, such as group party, dinner together and in the car, etc.
The external microphone works with the receiver. That amplifies the voice from
phone call. Or match a mobilephone with the receiver by the bluetooth.

very clearly.
Connect a MP3/iPhone/PC, etc. to the headphone's line-in jack with the wired
headphone cable, the hearing impaired people can listen to the music enjoyably.
