I thought I'd do a short review of all of the headphones I have personally owned. Might be useful for some. Feel free to ask questions if anything is unclear.
Sennheiser HD 600: I still own and love these headphones. IMO a little more detailed than the 650. The tonality is basically flawless. The resolution is exceptional and unmatched at this price. Timbre is to this day the best I've heard. The stage is relatively small and imaging bad. Really source-dependent. After a short break-in period incredibly comfortable. The bass is sadly boomy/not tight when boosted. (9/10)
Sennheiser HD 650/6XX: I don't like the mid-bass boost. It also seems a little less resolving than the HD 600/580. Otherw
