Cowin Active Noise Cancelling

Active Noise Cancelling (ANC) mainly focus on cancelling out lower frequency sounds like engines, aviation environment, trains, traffic noise etc, so our valuable customers can focus on their music, movies, or books without being disturbed by outside noises. Our ANC headphones incorporate a microchip that measures ambient sound and generate a waveform that is exact negative of the ambient sound and mix it with any audio signal our customers desires. Making it possible to listen to audio content without raising the volume excessively. Please do note, ANC does not cancel out noises like snoring, talking, music or high frequency sounds etc.
