Pretty much all has been said already. Excellent value, very good bass, mids and highs are a little laid back. Really comfortable. Perfect first pair of headphones for anyone looking to get a better musical experience from an iPod.

I bought this last year as a replacement for my Senn CX 300 and boy was I dissapointed. They sound absolutely flat, without anything resembling a good bass response. Mids are practically inexistent and highs, which are supposedly emphazised, are rough and pretty bad. I've given them to my brother since and he uses them to play Starcraft online so at least they are being put to good use.

These will provide very good isolation if you get the correct fit. I managed to do this by trying out all the tips affered. As others have noted, the is a little bit of distortion on the highs, which I've noticed slightly affects the vocals. The bass on these is really good, altough it fortunately doesn't drown the rest of the sound, which makes them a little balanced to my ears. Overall good value.
