[Rezound Sound]

I am just looking for full size headphones that don't leak any sound at high volumes. I am not too worried about keeping external sound out, so much as keeping internal sound in. They can be any price, but they have to be full size.

You're typically going to want to go with a large closed back phone with very thick earpads. ljokerl's headphone comparison thread does rate some of the isolation. Though the sound quality isn't very good, Bose headphones do have some very good isolation and comfort.
 
That said, you will have a tough time finding headphones that can isolate as much as IEMS.

X2.  And I'll add you want also want a strong clamping force.  Koss has some of those.

DJ headphones are my reference point.  Of the ones I have, the Pioneer HDJ-1000 isolates the best.
