Active Noise Canceling Technology
TDK Life on Record Noise Canceling Headphones reduce unwanted ambient sound to give you a better & more relaxed listening experience. Essentially, active noise reduction works by using a microphone on the outside of the headphone to pick up external ambient noise. This is then sent to a digital processor which generates an antiphase wave with the opposite polarity of the sound wave coming through the microphone. As a result, the external ambient noise is reduced within the enclosed listening space.
The NC400’s deliver effective noise reduction in such environments as aircrafts, trains, cars, buses and other public places where excessive ambient noise is present.
The active noise cancelling feature works with or without music playing through the headphones.
