[Suggestions 4] Good headphones, no sound leakage??

Hi. So I am a gamer with a bluesnowball mic (so no need for a gaming headset w' mic) but I am after a good pair of headphones, Over ear or on On-earwith little sound leakage?

My boyfriend is constantly frustrated with hearing my music and game as clearly as I hear it( even tho it doesn't sound loud to me, and isn't on full volume he hears all my games and teamspeak lol) either that or I am goingdeaf... anyone know of some nice headphones with no sound leakage?

I am after opinions of actual experience with any headphones. Since HMV dying outthere is less opportunities for me to try the headphones in person boo :(

Budget: 100-200

Some headphones I would like opinions on:
Seinhieser hd 25 : They look great, anyone have these can tell me about them?
AKG: No particular model, just anyone have any experience with this brand?
