Title: Not noise cancelling
Review: These headphones' only claim to noise-cancelling capabilities are the ear-pieces (which are very comfortable by the way). I had bought these specifically for a long plane flight, and the noise-cancelling function made no difference re: the engine noise. Worse, when I plugged them into the in-flight entertainment unit, turning on the noise-cancelling function effectively muted the sound of the system! Turning it off, however, amplified the sound coming from it, so much so that I had the volume on minimum and still felt it was a bit too loud (good thing I wasn't watching an action flick). To top it all off, there was a malfunction with the battery operating the noise-cancelling function, so it would just turn off by itself because it couldn't detect the battery anymore. While the sound quality is good and it muffles some sound due to it's earpieces, this is no noise-cancelling headphone.
