I am always slightly suspicious about audio products that appear to be heavily focussed on style and aesthetics. I actually received these free as part of a deal on a mini hifi system - and was not expecting great things. However, I was very suprised at the sound quality - in my opionon surpassing any other headphones I have heard at this price point. The bass is suprisingly solid and deep, with very good sensitivity and capability to go loud.
The quality of the materials used are excellent and they are very well constructed and maintain a feeling of quality while remaining very light and comfortable.
Possibly they do not fit quite a snugly as they might, but this is a very minor criticism; we all have different shaped heads.
An additional bonus is the microphone, and these are now my default choice for teleconferences duty. I have received a few strange looks while wearing these in the office though.... (possibly not the most professional looking headset).
At full full price these are probably still decent value - but at the discounted price of under twenty quid they are a steal.
