Noisy world, makes peace is precious. Special research and development of digital noise reduction technology, let you work, rest, or to travel, can fight at any time to enjoy the quiet. Noise and music don't have to compete for your ears. You can turn it down, still can hear each note, implementation technology unique space of tranquility to enjoy. A busy office, tumultuous lounge is not distract your attention. Digital noise reduction technology has realized the simulation of the system reach the environment noise sampling accuracy and reverse wave form accuracy, thus has a good noise reduction effect. Adopting digital equalizer for signal processing, and further enhance the noise reduction effect, ensure the good match of audio output and acoustic characteristics. Noise cancelling headphones acoustic system can realize high frequency sensitivity, eliminates the general noise control system is often too exaggerated bass effect. Digital amplifier technology, the improved with among them, it is done through high precision output full digital processing.
