I bought these headphones six months ago and have been waiting for something to go wrong before I review them. Sadly, that day has come. I've worn them very comfortably and been so, so impressed with the quality of the sound, given their price. They are far better than any of the $50 on-ear headphones I have owned and far, far better than standard Apple headphones. Better in comfort and sound, that is. The earpieces themselves have stayed together wonderfully, apart from some paint harmlessly chipping off and the occasional moment where I realize I'm missing a squishy ear-cup and my world turns upside down until, yes, I've found it. Every. Time. The only real fault, however, is in the durability of the cord at the jack-end. That is, the quarter inch of cord before it plugs in to the device. There's an extra wrapping of rubber there for reinforcement, but it hasn't done its job. Granted, about a week ago I lost the handy hard-shell case which came with the purchase and have only noticed the damage since then, but they really ought to last longer than they have. Without the case which lets this particular segment of the cord rest at ease, I've been wrapping the headphones around my iPod, which leaves it bent over itself, and ultimately cracking the rubber. At present, the reinforcement rubber is completely split open and useless, and the wires inside are exposed. As far as I can tell, the bare wires aren't yet affecting the sound quality, but I'm sure that's not far off.
Pros: great middle frequency range, great high frequency range, good low frequency range, look good, very effective case, comfortable and snug ear-cups (very subjective)
Cons: jack-end doesn't last, lose the case and you're screwed
