Active Noise Cancelling (ANC)

The ANC feature reduces ambient low-frequency noise. To activate or deactivate ANC, press the dedicated ANC button. The ANC indicator light will illuminate when ANC is active.

Note: ANC is most effective at reducing consistent low-frequency sounds like engine hums, air conditioning noise, or train sounds. It may not completely eliminate sudden or high-frequency noises like voices or car horns.
