Summary: Good sound, though bass is a little light, but well defined. not quite up to Bose standards though much cheaper. You have to be careful with the folding parts which look a bit fragile. The noise cancelling is fine for most situations, trains, planes and automobiles etc.
Summary: Bought these in preparation fro a long haul flight. Have used them at work in large open plan office and they kill the general background noise well. Comfortable to wear for several hours. Music OK when traveling on buses/trains where noise reduction also good.
Summary: These have excellent noise reduction for the plane, train and also an open plan office. Great fit, not too heavy. Not experienced the noise interference mentioned by others of the cord cable but then again I use them whilst sat rather than on the move.
Summary: Fantastic noise cancelling, and probably the best alternative to the Bose Quiet Comfort 3 as far as noise cancelling headphones go (rechargeable by USB too, beat that Bose), the only downside is that your neighbours probably won't appreciate the music leaking from your headphones.
Summary: I've had these earphones now for 5 months and they are still going strong. I've only had to charge them twice so far! I use these about 3 hours a week when commuting on the tube, and so far they have very little wear.
Summary: Nicely balanced sound, noise cancelling very effective and as other reviews suggest, does not take away or add to the sound when listening. Very comfortable. Pouch a tad small and the stainless surfaces do rub against each other when in there. Very pleased with purchase and would do so again.
