I like my Sennheiser HD600s pretty well, especially with Sonarworks correction. I've been using Audio Technica ATH M50s for location where I need a sealed can, but I got tired of the big bump on the low end, so I splurged for a pair of the ADAM SP-5s. They have amazing imaging and are intensely revealing, but I'm still getting used to mixing on them. They are like a sports car with insanely quick reflexes. Wait, that sounds like a bass we all know and love.....
