I got these about a year ago when they were 14.99, they are currently listed at 10 more but they are still well worth it in my opinion. The range on them is very good able to handle quite a lot of bass without clipping while the high end is crystal clear.
I'll admit I mainly waste these playing mp3's from my phone but when I hooked them up to my pc and used ASIO drivers for output with flac files and cds you can really see what these things can do, as the sound is much more open and bright.
Build quality is great, after a year theres no sign of wear (although I do look after things) and the sound is better than when they were first used. I noticed this after a few weeks of use, so if your not 100% happy with the sound quality I'd say break 'em in for a bit first before forming opinions on the quality.
