Sony MDR-NC500D is the world’s first noise-canceling headphones with noise digital signal processing with a newly developed high speed software engine DNC. The result is about 99% external noise is cut off. Daily sounds from air craft, trains and other vehicles is cut off to a very great extent when using the head phones.

DNC Multimedia?!?
