Don't really have any recommendations, I use AKG M70's. But wish I had something better.
But when working with a (must of been fairly deaf) vocalist once, and headphone bleedthrough was becoming an issue... I had him pop in his ipod earbuds into the dist. amp, then put a pair of safety earmuffs over the top. Fixed the bleed through and he was happy/I was happy, but it sure didn't look very comfortable.
