Okay well those are cheaper than ithought... How much of a difference would i hear from any of the over ears with the fiio e11 or any ofther $50 amplifier?

Did you mean, just the mm500-x? And not the mm550-x? And out of the over ear headphones which ones would you say sound the best? I really dont mind ugly looking or some portability flaws, i am mostly concerned with the nicest sounding cans i can get for $200-$250 thanks so much man.

Okay so i am new to the world of quality headphones. I am not a DJ or anything like that but I do have a desire for really really nice sounding headphones. My budget is $300 MAX and $200 minimum. Right now im thinking HD 598, mm500-x, tma-1... Also, i am not sure that i want to go with open...
