sup guys

Ok ... recommendations please for a pair of;

-Stereo MP3 headphones
-Look good
-Soundproof (So I can't hear what's going on outside 'em and people outside can't hear the music)
-Good quality
-Cheap ... Pref .... <£20

I was recommended the Koss KSC75's for their quality and price; £13 =0; but it seems their noise cancelling is non-existent.
I'm using a pair of EP630's atm ... which ain't too bad but the sound leak whether they're in or out of my ear is crazy ...

cheers
