How do I turn on the Active Noise Cancelling feature?
Press the ANC (Noise-Canceling) switch to the ON position, and the blue LED light will turn on. The noise cancelling function works primarily for low-frequency noise such as in airplanes, buses, or trains, though the effect may vary depending on how you wear the headphones.
