Bose QuietComfort 2 Acoustic Noise Cancelling Headphones

Bose QuietComfort 2 Acoustic Noise Cancelling Headphones Bose has taken its hugely popular QuietComfort Headphones to a whole new level. They still have the same exceptionally comfortable, lightweight ear cushions, and state-of-the-art TriPort headset technology that filters and cancels the sound waves of outside noise (including high-decibel engine roar, wind noise and other aircraft sounds). But now the already wonderful audio sound has been further enhanced for even fuller, richer sound, whether you’re listening to music or watching the in-flight movie. And if you use the noise-reduction feature on its own (without any audio signal), the cord may be removed from the earcup for wire-free comfort. Rotating earcups fold flat for easy storage. Includes 36” extension cord for media players, airplane jack adapters, belt clip, and carrying bag. Takes one AAA battery (included). Case measures 7¾ x 6½ x 1¾". (7 oz)
