Just buy them already!
I've read a few reviews on these headphones, getting right into the nitty gritty about sound quality etc. To be honest some of these put me off. But get these for the right price and you won't regret it. Ok so they may leak a little sound and not match up to a pair costing £300, but let's face it these are mostly about style and on that front they win over most other headphones out there.
Sound is fine, nothing incredible. They isolate outside sound pretty well and the silicone cups are really comfortable, infinitely more so than the Nomadics. They're also lightweight, adding to the usabilitry. So if you want the best sounding headphones, go spend a lot of money. If you have a bit of spare cash or looking for a nice gift for someone with an awesome sense of style then get these.
