so i did a little research and i'm thinking of the sony mdr 7506,if i can get them for a decent price. i read nothing but rave reviews. i want them mainly for music playback and studio type monitoring/mixing/recording of techno/electronic/rap/rock. they can also be used for dj'ing (they can flip up) if i needed to (though this will be a very small part of their use). i think i might be able to find a pair for 50-75 on ebay. hopefully towards the lower #. any experience w/ these.
