New Bose QuietComfort 2 Acoustic Noise Cancelling Headphones.

Bose® QuietComfort® 2 Acoustic Noise Cancelling® headphones electronically identify and reduce unwanted noise while faithfully preserving the music, speech or peaceful serenity.

The Bose® patented Acoustic Noise Cancelling® headphone technologies in QuietComfort® and QuietComfort® 2 headphones use microphones in the earcups that actively monitor the sounds you hear. The difference between the existing sound and the desired sound is then electronically processed. The driver within the earcup creates a correction signal that is opposite to the effect of the outside noise and combines with passive attenuation to dramatically reduce it.
