As befitting the brand (and the price), the sound quality you get from these headphones is near perfect. But it's not an all-rounder. The box promotes the bass sound you get from these headphones, and you certainly get it. A bit too much at times, in fact. It depends on what you're listening to. Whilst it never sounds like a large truck going past, as can happen with cheapo headphones, the bass can somewhat overwhelm the other levels in particularly bass-heavy music. It's better for bringing out the bass in music that's already balanced. If you can try before you buy, do.
Apart from that, I don't have any major complaints. They are comfortable to wear, don't make your ears get hot after a long time listening, and twist in all sorts of directions for those of us with oddly shaped heads. It's a minor thing, I know, but I've had headphones where the jack just flies out of the socket at the slightest turn of the head, so I was pleased the one attached to the lead here had some resistance.
My wife also wants me to point out that these aren't very suitable for using on a train unless you want an ASBO. It's not their bulky size that's the issue (because they're lightweight with it), but the fact that whilst they're very good at keeping other sounds out, they're not quite so good at keeping the sound of what you're listening to in, even at reasonably low volumes. So mainly for home use, then.
On a sidenote, I plugged these into my Marshall practice amp to see how they fared, and they are by far the best headphones I've ever tried. They pick up levels just lost in the background when using the amp's own speaker. So guitarists who play hard rock or metal should add an extra star to my rating above.
