mode based on your listening preferences and environment.

Noise cancelling modes

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.

Charge the headphones

2. Plug the other end into a USB wall charger or computer that is powered on.
