Bought these to replace a pair of Sennheisers in which one ear had stopped working. Extremely impressed, especially for the price. Look, feel and sound like earphones at twice or three times the price. I listen to a wide variety of music, from rock to contemporary classical and everything in between, and they sound great whatever I'm listening too.
Update: Been listening to these for a few days now and I'm more impressed than ever. The detail is superb! I've been browsing my iPod listening to things with new ears!
