Is the Shure Srh840a worth the upgrade from the Sony WH-1000XM6?
Verdict
Downgrade
The Shure Srh840a actually scores 17.3 points below the Sony WH-1000XM6, so on aggregate review consensus this is a step backwards. It loses ground on sound (9.0 to 8.0) and value (8.2 to 7.5). On paper: driver size 30 mm to 40 mm. Worth checking: active noise cancelling goes Yes to No and weight goes 254 g to 273 g. It is at least $229 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.
