Average Reviews:
(More customer reviews)Some of the reviewers here have complained of a hum when the noise reduction switch is engaged.
Mine have no such hum. When I turn them on, much of the extraneous background noise immediately disappears. The sound quality is crisp and clear and much more defined than when the anti-noise technology is disengaged.To be sure I tested them in a quiet environment and the sound was still vastly better.
I do think these headphones are somewhat inferior to the Bose® QuietComfort® 3 Acoustic Noise Cancelling® Headphones. But the audio difference is slight and the economic advantage is significant.
I recommend these headphones.
