The difference between this and what else you can get for $30 is incredible. This is a huge step up from my (also $30) Skullcandy headphones. I hear things I haven't heard before in songs.

The construction is solid, I feel like I could step on them with minimal damage. The design, including the ComfortZone switch, ensures that the headphones will not leave your head unless you want them to. It doesn't put too much pressure on your head or ears.

They fold up into a little bag. Good enough if you carry a purse/backpack/European carryall, but you can't stuff them into a pocket.

They bleed a tiny bit if you crank the volume way up. Maybe a problem if you're trying to stealthily listen to music in a cave.

Also, they don't block out sound very well. These might not be the best choice for loud environments.

Also Koss has a lifetime warranty, remember that.
