Excellent “Elite”, wonderful life.
The technology of Elite products are based on DSP chip which has
high-spend and multi-core calculation and advanced algorithm. The
Elite products will provide you a high-quality sound by the
exclusive audio signal processing function and perfect bionic
perception to the sound.
Optimum series is generated by the newest technology which provide
you with the clearly hearing by up to 36 channel signal processing,
10channel DDRC adjustable compression, super quiet technology and
5th generation feedback cancellation.
Up to 36 channel signal processing
Up to 36 channel of signal processing and bionic technology, it can
distinguish the noise and speech signal, weak the loud sound,
restore the original sound, and give you a clearly hearing and
wonderful life.
Up to 10 channel adjustable compression DDRC
Optimum series with up to 10 channel adjustable compression DDRC,
accurately fitting the different audiogram well, meeting the
