Is the Shure Srh840a worth the upgrade from the Sennheiser HDB 630?
Verdict
Downgrade
The Shure Srh840a actually scores 14.0 points below the Sennheiser HDB 630, so on aggregate review consensus this is a step backwards. It loses ground on sound (9.4 to 8.0) and value (8.4 to 7.5). On paper: weight 311 g to 273 g. Worth checking: active noise cancelling goes Yes to No and driver size goes 42 mm to 40 mm. It is at least $281 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.
