The RP21's sound far better than they should for the $149 (easily gotten for $99). They have very good bass weight and depth. The mids are reasonably open and transparent. The highs are a little chalky and dry, but removing the foam helps this somewhat (but of course voids the warranty). The stock earpads could be a lot better - the RP21's are much more comfortable with pads from a Beyerdynamic DT770 (but you need to get the pleather pads or you lose a lot of bass). The RP21 isolated very well, better than a lot of other closed cans.

A very good closed headphone for the money.
