Strange, the general consensus seems to be that this is what HD650 do.
Give them some time, when I first got mine 3yrs ago (coming from HD555 at home, PX100 at work) I was somewhat shocked, they didn't sound at all like I had expected, which was HD555 but "better" in all areas. To me mine sounded rough and uncouth (I previously have described my first impression of them as "aggressive" but no one here seemed to believe that) I was OMG what have I done, blown $400, even after the 40-80 hours burn-in (that I didn't really believe, but what the hell) still not liking - then at some point it clicked and all was good, then a few weeks later it shifted again becoming even better - just my subjective impressions. I'm sure glad I didn't give up on them - still loving them.
Maybe coming from IEMs your expectations are unrealistic, I can't make any comments on relative presentations as I can't use IEMs
