"Excellent headphones."

Feature:
These headphones were well thought out. Replaceable cable, automatically adjusting headband, and conforming ear cups are just some of the well thought out features of this pair of headphones. I researched this a lot before I bought them, but I found some issues that I was worried about that weren't covered in any reviews I'd read, so here's some of those. Sound leakage: Being semi-open, I was worried that there'd be a lot of sound leakage. I plan on using these in the studios and a lot of bleed would've been a problem. To get their excellent sound, they need to be open a little, but these leak almost no sound at normal volume levels. If you tend to listen to your music loudly, there may be some leakage that occurs, but typically not more than the sound of loud wisper. Comfort: These are supra-aural headphones. They sit on your ear. That's what they're intended to do. If that bothers you, buy the 240s which should have the same sound signature, but are circum-aural. As far as supra-aurals go, these are great. Due to the self adjusting straps and conforming ear cups, there is very little pressure against your ears. These headphones are the most comfortable supra-aurals I've ever tried.

Quality:
These things seem extremely durable. The support bars for the headband move around enough to not be a problem with travel. I've read several reviews about these things lasting years and years.

Value:
These headphones are amazing. Worth every single penny and then some.

Desirability:
I love the (almost retro) look of these things. It's just me, but I think these things look great.

Sound:
This is one problem I have with rating this product. I haven't listened to it enough to accurately judge the sound quality. However, I can say that the second I plugged it in and listened to the first track on a CD I could already hear things in the mix that I'd never heard. There's a review over at head-fi that does a much better job of describing the sound characteristics than I could do.

Ease of Use:
They're headphones.... the self adjusting strap is nice though.

Support:
Never dealt with it.

Overall:
These headphones are awesome. The review over at head-fi was the primary reason I bought these. If you're even considering buying these, go check out that review.
