PBlockYeah, its not an unusual pattern for the m50x to be top 5 in most lists its involved in. A shame that things like B&W, AKG, and funny enough, better Audiotechnica headphones get left out.
MDKrinklesEven things with the value of the AD500X :(
Seriously, they're about $80USD less than the M50X on Amazon. Bargain if you ask me.
That said, I voted for the M50X because I need some close-backs.
