Is the Beyerdynamic DT 990 Pro worth the upgrade from the Beyerdynamic DT 270 Pro?
Verdict
Downgrade
The Beyerdynamic DT 990 Pro actually scores 4.8 points below the Beyerdynamic DT 270 Pro, so on aggregate review consensus this is a step backwards. It loses ground on value (9.0 to 8.0). On paper: driver size 42 mm to 45 mm. Worth checking: weight goes 194 g to 250 g and usb-c goes Yes to No. And it costs $70 more for a lower score, which is hard to justify on the data alone. 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 "DT 270 Pro 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.
