so many jokes, so little time! :P
really though what i imagine the OP is looking for is something along the lines of http://www.amazon.co.uk/Roccat-Solid-Surround-Gaming-Headset/dp/B00275C2L6/ref=sr_1_1?ie=UTF8&qid=1289551315&sr=8-1
a vibration function is a feature of various models of gaming headsets, however if its a decent set of headphones you're looking for they are definitely not it, however many positive reviews there
are about them, the SQ is appalling and the overall build quality leaves a lot to be desired.
Really i think the best thing to do is get a decent set of stereo HP's with a solid base response, the whole vibration thing is a gimmick as is "true" 5.1. A pair of HD555's probably wouldn't be a bad place to start.
in short if you really really want a pair of vibrating headphones, your best bet is to buy a decent set of stereo cans and tape your phone to them :)
