Everything is good about the Bose Quiet Comfort headphones. They are comfortable, excellent sound, amazing noise cancelling and batteries last a good while. Plus you can get spares easily direct from Bose to keep them in good condition. plastic side slotting pieces can't be replaced and I find can break after a few years, but easily taped back together. The best headphones I have ever worn.

I've owned many pairs of headphones and the Bose Quiet Comfort 2 headphones are by far the best I've have ever owned!

They don't cancel out all noises, which I don't think any of the noise cancelling headphones can, but they do wonders with reducing the amount of noise around you so you can enjoy your music even more so than normal.

They have great sound quality, they really do. The highs are crisp, quite literally, and the lows aren't bellowing out of the speakers to deafen you, they are just right. :-) These headphones really help out with giving you perfect, clear sounds that helps you bring your music to life.

The price isn't for the faint of heart. I'm just lucky enough that my company will pay for them as part of my compensation package. If you have 350 to blow on these headphones, do it. They make travelling fun, and they make music sound better than ever, just like Bose normally does.
