They are extremely comfortable, a bit heavy but the fit is so good you don't notice it. The best part is the sound - absolutely fantastic. I don't know how it could be any better, perfect balance with the highs and the lows were they need to be and with perfect clarity. The noise cancelling really helps when in those noisy environments. Don't like that they don't work if the battery goes out. Apparently the battery is for the noise cancelling feature.
