i have to disagree with the previous review, ive had these for two months now. I gave them a day of music at a low volume to wear them in and after that they sounded great. Quality bass, mids and highs, comparable in quality to my sennheiser pxc250's, the bass on these being so much better!
Now that play.com are stocking these i would highly recommend them! The frequency response curve is impressive when compared to much more expensive in-ear sets such as those from shure. (search for these as they help when comparing earphones)
Good sound quality
Nice bass and all round sound production
Good noise isolation
Colour coded earphones! (red and blue)
case could be a bit better quality!
