I currently have the XB500, XB700 and DT770/80s for cans.
XB500 is too boxy, although i like the punch. Lacking just a hint of sub bass compared to the XB700.
XB700 is more resolving than the XB500, I would prefer it be a bit more darker.
DT770/80, still my fav but has a sharp treble spike before 10k.
Comparing bass quantity which comes out first?
I want a nice dark, laid back sound with lots of sub bass without being boxy. Pro700mkii's sound interesting but I worry they will not have the sub bass of the m100 or q40.
