I see, i will probably go with the X2 then, and its cheapier than HD600 in my country, Thanks!

So, after some time with ad700x when i stopped to listen my m50 again i didn`t really like the sound, but i think that happened because the mids that aren`t really present, this happens with the x2? And thanks for the reply

Hey guys, so, by the end of the year i want to upgrade my headphones, and i don't know which one to choose, Fidelio x2 or hd600. I used to like my m50s, then i bought the shp9500 for gaming and i didn't like for either gaming or music, i sold it, and in the end i bought an ad700x and i love it...
