Please do not buy these headphones. Don't get me wrong, I bought them a couple weeks ago and love them to bits in terms of sound quality and comfort, but they've been a nightmare. It started, after owning them for a single day that the headphone jack broke. Although this was partially my fault, and there is probably nothing uncharacteristic about the jack, but i've noticed a couple of flaws in case this happened, which it obviously did. Firstly, the piece just down the cord from the jack which is obviously just to help plug it in etc, is extremely large, therefore making it easy for pressure to be applied to it, breaking the jack. Also, if the jack is broken, it may not seem like a problem, just replace the whole cord right? $10 or so shouldn't be a problem? except the cord is permanently attached to the headphones, and therefore renders it useless. Also, having now owned them for two weeks i've noticed the cheap plastic structure isn't just tacky, but structually unsound. Upon examining my headphones i've noticed several hairline (and some not so hairline) cracks all across the plastic arms, one of which is halfway down the width of the arm, and I would personally give it another few weeks of usage before they broke altogether. So again, top headphones - but durability is appalling, not worth anywhere near the 100 pounds (roughly USD$170) I paid for them. Thoroughly disappointed.
