I'm on my 3rd pair of these because I love the sound but inevitably, these will crack along the headband somewhere. For me, it has always been in the same general spot - when folding them down, a bit of stress is put on the plastic and after months of use, hairline cracks are bound to appear. For 300.00 they shouldn't do this or Monster should replace (in which they don't).
I bought these about 6 months ago now. I wanted to really use them for a while before I could give a proper review. I feel like the sound quality is really good, but I've had $50 dollar Skull Candy headphones with pretty much the same sound quality. The in-line mic doesn't work. So I have to take off the headphones and unplug them every time I get a call. I'm in the middle of getting them to send me a new cord, which is literally an ordeal. It's been over a month I'm still waiting for the replacement. I think next time I'll give them a pass.
