Why do you want or need noise canceling headphones? Well they serve at least two purposes. First is for ambient noise reduction. That means if you are sitting in a place where there is a lot of annoying ambient noise, noise canceling headphones will reduce or entirely eliminate the noise.
They work by emitting a sound frequency that while hard to detect by your ears, helps mask other noises. They seem to work best for low frequency noises and hums. For example, the hum of an airplane engine can be masked out, though a baby's cry will be merely dampened. Noise canceling headphones also create a close to air-tight barrier around your ears that prevents vibrations and noise from getting to your ears. this is particularly convenient for over-the-ear headphones that work via this same principle to get quality sound into your ears. Denon uses two methods of noise-reduction in each speaker. One helps reduce vibration in the unit itself, and the other method as I said, works on reducing external ambient noise.
