Our active noise reduction electro-circuit is unique so that rather than using large earcups and considerable headband force to reduce aircraft noise, we structured the headset in a more proper way with our innovated electro-circuit and excellent chip material. As it is known to us that a microphone is established for collecting noise sample, which is used for generating a reversed sound wave to reduce the noise. Thanks to our innovated technology and skills, we have conquered the difficulty in balancing the feed back. As a result, the noise sample collecting microphones on our headsets are set inside of the earcup. This inimitable technique enlarges the anti-noise intensity as 1.5 times comparing to the congener products. Other than digital electro-circuit, our noise attenuation facilities are based on Analog-Circuits electro-circuit technique, through which a more veracious sound would be generated.
