Good, but not great
I've gone through 3 pairs of Creative EP830s over a few years and decided to change as my last pair had stopped working (I guess the cable got damaged).
Comparing these headphones to them, they are far quieter and do not have as much deep bass as my other headphones did. I have to have my MP3 Player on full volume to get any bass out of these things.
They are also very fiddly to put into your ear.
