content: I've owned various noise cancelling headphones, from expensive Bose Quiet Comfort to cheaper models. I've had $60 noise-cancelling headphones do a great job at cancelling noise. I know how noise-cancelling feels, I know what to expect.I bought these on my way to the airport as I had forgotten mine... I wasn't risking much for the price. They are comfortable, I like that they nicely feet around the ear. The sound quality is decent. The noise cancellation absent.In fact, activating noise cancellation will actually INCREASE noise by adding a white noise. In the airplane, I tried switching it on and off... all I could perceive was a shift in the frequency of the woosh, but the volume of the noise was lower when noise cancellation was turned off.I don't know by which stretch of the imagination these can be called noise-cancelling headphones. If you don't care about noise-cancellation, you can buy a higher quality regular model, if you do, by all means stay away.
