Is the Sennheiser HDB 630 worth the upgrade from the Beyerdynamic DT 990 Pro?
Verdict
Clear upgrade
Going from the Beyerdynamic DT 990 Pro to the Sennheiser HDB 630 buys you 21.7 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in sound (7.5 to 9.4). On paper it adds active noise cancelling, transparency mode and companion app. Worth checking: weight goes 250 g to 311 g and driver size goes 45 mm to 42 mm. One caution: this steps down a line tier (DT 990 Pro to HDB 630), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. That costs $250 more, or about $12 per point of score - reasonable value for the jump. 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.
