Is the Beyerdynamic DT 990 Pro worth the upgrade from the Bose QuietComfort Headphones (2nd Gen)?
Verdict
Downgrade
The Beyerdynamic DT 990 Pro actually scores 22.4 points below the Bose QuietComfort Headphones (2nd Gen), so on aggregate review consensus this is a step backwards. The gains are concentrated in value (7.5 to 8.0). You do give up ground on sound (8.2 to 7.5). On paper: driver size 40 mm to 45 mm. Worth checking: active noise cancelling goes Yes to No and weight goes 236 g to 250 g. It is at least $159 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.
