Hello rpgwizard, ok thanks, but i think i'll go for the pro 900 anyways because i'm starting to listen more and more to other kinds of music (piano music, reggae..) so i gues i need these high highs too. also the looks of the pro 900 is just stunning. the looks of the m-audio is comparable to the beyerdynamics, it's a studio headphone. but i will take the fiio e17 ;)
but you are making it harder for me to choose the pro900 now by saying all this... :D especially becuase of this freaking price difference between both.... but i found a audiophile's music shop in my town, i will go and take a look soon.
nothing like experiencing them yourself
