Tried these out on a week long holiday. With 28 hours battery life, did not have to recharge at any point! The noise cancelling feature worked well on the plane and allowed me to sleep much easier. You never notice how much background sound there is around you until you put these on! The music quality is good. I find you can hear greater detail from instruments then any standard pair of headphones. The controls are perfect and represent real thought in the engineering process. For example the touch pad on the right ear is fantastic (volume, track selection, pause/play and the feature that switches to ambient so you can hear someone without taking the headphones off).

Comfortable to wear, long battery life, shuts out ambient noise and delivers crisp sound with good bass. What's not to like? OK the price is at the premium end of the spectrum but you get what you pay for. I'd recommend them to rock music fans.

Very happy with my purchase and really enjoying listening to my music
