I like the bass signature found in Beats, but I dont like beats because honestly, every tool I know has one. As of now, I own a pair of Sennheiser HD 439's which are circumaural open back headphones with great soundstage and I really cant complain about it. But Because of its lack in bass, I only use it to watch movies or listen to non EDM or dubstep music. My budget is $200. I have heard mixed reviews of the following headphones: V-Moda Cross Fade LP and LP2 (durable, decent bass, but not exactly a basshead headphone) ATH-M50( extreme clamping force, accurate bass but not ear rattling like i want) M-Audio Q40 (Bass Monsters, basically subwoofers, but the earpads are bad..) I always was interested in the Ultrasones, but I can't decide which would be better for bass.
