KF-910B In The Ear Hearing Aids  (Cryptotype Hearing Aids)

Future:

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.
