Coming back to this, my Senn 438's don't leak that much sound even on full blast. Enough to where you can make out the song from a couple feet away but it gets incomprehensible fairly quickly.
Take it from me, Goafer, and R_A Sennheisers are totally worth it. From the 202's and up.
I just bought a HTC Thunderbolt. Hello 4G whenever they finish setting it up here (it's in the works). Mainly though, 3G is close to my home internet, and I can get my laptop online when I'm not at home now. Huzzah.
