Wide & open with quite excellent positioning (only less so comparing to balanced T1). I have not yet hear other phones (i.e. K701, HD600, HE-5LE) that have more natural and accurate soundstage than DT880/600 with my systems. I just tried some vocal tracks and found some has excellent radial positioning (Judy Collins sings Dylan) and another (Mary Black: By the time it gets dark) has very close presentation ("between the ear"?). It seems to me more like it is just the way they are recorded.
There is no fake soundstage at all even with my DLIII DAC and single-ended CSP2+. (It seems ZX's cable and Audio-GD's DI+PSU also bumped up the sonic positioning a few levels ). My balanced setup has even higher resolution in the radial direction.
