KF-901 Behind The Ear Hearing Aids

Future:

Use our hearing aids.hearing loss of 65% of the people will still hear vioces outside.
There are some important indexes for a Hearing Aid.
1. Power increasing range

2. Stability of output signal and timbre disposal
3. Max distortion index and disposal function
4. The earphone quality All the above factory effect the Hearing Aid quality
5. Our hearing aid have design manostat electrocircuit on PCB,The manostat electrocircuit can leach outside noise and protect eardrum.
