Active Noise Control
What is ANC (Active Noise Control) ?
Noise-Canceling technology electronically identifies and reduces unwanted ambient noise by combinations of a sound-isolated headphone, a built-in compact microphone, and the noise filter circuit.
A built-in microprocessor identifies unwanted ambient noise and sends equal-but-opposite canceling signal to the headphones. As a result, you can enjoy the clear sound of the music from the audio device.
