|Beats Pro, PDX-2000, & Limited Edition PMC-007|
For your background reference I like B&O speakers, Infinities, B&Ws, KEFs, JLs, pro JBL (why is their pro gear so good and consumer shit so shit???), and EVs, I like the sound of larger subs 15" and 18"s. I've compared these against my other DJ Headphones, I often seek 50MM drivers but have had sennhisers low and high end (the ones you see people on TV with, my ex "borrowed" them I think they are Sennheiser HD25-1 II), Sony MdR-600 and MdR700, Bose QC3, and Yamaha's which sound great but break like a Range Rover.
Just a tip buy them at the official monster outlet and there are often coupon codes to stack if you look. I was able to find a 25% off (yeah!), I choose free standard shipping which took a bit over a week but apparently the fedex guy forgot where I lived the first scheduled delivery day. http://www.monstercable.com/outletstore/
