Is the Beyerdynamic DT 990 Pro worth the upgrade from the Sennheiser HDB 630?
Verdict
Downgrade
The Beyerdynamic DT 990 Pro actually scores 21.7 points below the Sennheiser HDB 630, so on aggregate review consensus this is a step backwards. It loses ground on sound (9.4 to 7.5). On paper: weight 311 g to 250 g and driver size 42 mm to 45 mm. Worth checking: active noise cancelling goes Yes to No and transparency mode goes Yes to No. It is at least $250 cheaper, so the lower score comes with a saving. 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 "HDB 630 to DT 990 Pro". 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.
