Is the Bose QuietComfort Headphones (2nd Gen) worth the upgrade from the Beyerdynamic DT 990 Pro?
Verdict
Clear upgrade
Going from the Beyerdynamic DT 990 Pro to the Bose QuietComfort Headphones (2nd Gen) buys you 22.4 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 8.2). You do give up ground on value (8.0 to 7.5). On paper: active noise cancelling, weight 250 g to 236 g and transparency mode. Worth checking: driver size goes 45 mm to 40 mm. One caution: this steps down a line tier (DT 990 Pro to QuietComfort Headphones (2nd Gen)), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. That costs $159 more, or about $7 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.
