what is noise cancelling for headphones
Showing 13.5ÏEX earphones with noise cancellation from Sony Walkman Series NW-S705F. Noise-cancelling headphones are headphones that reduce unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing. Noise cancellation makes it possible to listen to music without raising the volume excessively. It can also help a passenger sleep in a noisy vehicle such as an airliner.
