The ultra-quiet feature allows you to enjoy the quiet, tranquil life
Hearing aids amplify the sound, at the same time, the background noise along with zoom, which gives the original hearing not good,take annoying noise to who in a quiet hearing-impaired. Hearing aid, uses a unique ultra-quiet function, different amplification characteristics for the different voices and background noise amplification to minimize, life buzzing, Chi Chi and other subtle noise is shut out, easy to solve the problem of noise interference and allows you to listen more clearly.

Automatic volume control the WDRC wide dynamic range compression
Four-channel independent the WDRC wide dynamic compression technology, let all sound amplification in listening to the scope of the domain, automatic volume control mode, suit for a variety of hearing loss.

Independent light sound, strong voice of fine-tuning
Softly strong voice independent fine-tuning of hearing aids for the hearing to listen to a domain regulation, give priority to ensuring the sound soft and clear. Audio compression listening domain, effectively eliminate revive the phenomenon is to listen to a narrow threshold of patients can easily listen to.

Four-channel all-digital precision to compensate for your hearing loss
4-channel wide dynamic compression technology, to ensure that the sound amplification with hearing loss a good match. The four-channel independent regulation also increases the flexibility of fitting, better meet the impaired patient different needs.

Automatically swept muffler feedback
Use phase to eliminate the acoustic feedback technology to eliminate the feedback at one step. Automatic sweep system, the feedback signal is detected, contrary to the feedback signal negative wave is given in an instant, cut the feedback. To ensure at the high-gain hearing aids premise, you can still listening free.

The maximum output sound protection, protect your hearing
Hearing aids care for your residual hearing. The maximum output sound protection to prevent damage caused by the sudden strong noise on your hearing, protect your residual hearing effectvely.

A directional microphone capabilities
Because the low signal in a noisy environment, hearing-impaired often can not hear clear, directional microphone technology to take new feelings to listen to a noisy environment. Directional microphone is divided into front and rear microphone, RP technology to eliminate the noisy background noise, applicate delay technology to ensure a useful voice full zoom, directional microphone makes listening in noisy environments easier.

Indicating tone, adjustable volume
Low voltage prompt, the program conversion tips, and convenience for the user's use of hearing aids. When using the program button, clear to the conversion to which program. When the battery voltage is low, hearing aids intelligently tone sounds to alert the user to replace the battery. Indicating tone, adjustable volume, allowing the user to select their favorite prompt notification volume tone and comfort, to bring more user-friendly design features.
