Is the Sennheiser HD 650 worth the upgrade from the Beyerdynamic DT 1770 Pro Mkii?
Verdict
Clear upgrade
Going from the Beyerdynamic DT 1770 Pro Mkii to the Sennheiser HD 650 buys you 13.0 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in sound (7.0 to 9.0) and value (6.5 to 7.5). On paper: weight 377 g to 260 g. Worth checking: driver size goes 45 mm to 42 mm. One caution: this steps down a line tier (DT 1770 Pro Mkii to HD 650), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. It's also $219 cheaper, which makes this an easy call. If your current pair is worn out or the gains line up with how you listen, this one is worth the money.
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 "DT 1770 Pro Mkii to HD 650". 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.
