Your comments are spot on with my impressions and I've had my pair for over a year. Detailed, but very boring, heavy, and clamps my head. Although doesn't really reach very low in the bass department either.

Honestly, if I do not have something to compare (ie. M50) with me, I'd think that SRH840 would be fine. Because after all, they are considered cans in the same level, so rest assured these are really good cans. Just that some prefer colored, some prefer neutral. The quality is still there.

M50 is harsh and muddy compared to these. Srh840 is king of closed backs under $200 for me.
