I do not know what HIFI people are thinking about , I am a professional musician, I have used AKG k701 for long time when i was still studying in austria. then i heard the HD650 and 600, I was in love with the 650. I have tried hd 700, 800, BD DT880 990 (some from my studio), never changed my mind . until I Heard the fidelio X1, bought it loved it(still love my 650 bit more). last month I bought the X2 from amazon. NO way, this headphone is no way batter than the X1. you feel you are out side of the music, looking at it. and do you hear the treble, it jumps like mad. mid is far away , bass is good , need a bit more body, maybe better than X1? i do not know for sure. but all in all, it is not musical , you are not in the music, you are outside , you hear a lot of sound, (I find the HD800 give me the same feeling). do you want music or you want the tectonic headphones?
BTW , i heard the MDR Z1R, I feel it is a music instrument, I will get it some time soon.
I made an account here just to tell you what i think and feel about this matte, I bought the X2 because people saying is better, much better , improvement......
