Is the Beyerdynamic DT 1770 Pro Mkii worth the upgrade from the Sennheiser HD 650?
Verdict
Downgrade
The Beyerdynamic DT 1770 Pro Mkii actually scores 13.0 points below the Sennheiser HD 650, so on aggregate review consensus this is a step backwards. It loses ground on sound (9.0 to 7.0) and value (7.5 to 6.5). On paper: driver size 42 mm to 45 mm. Worth checking: weight goes 260 g to 377 g. And it costs $219 more for a lower score, which is hard to justify on the data alone. Only worth it if a specific feature above matters more to you than overall quality does.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.

About this verdict
Direction matters here: this page answers "HD 650 to DT 1770 Pro Mkii". The other direction is a separate question with a different answer. Scores blend published review verdicts across over-ear and shift as new reviews land, so a marginal call today may not be one next quarter.
