Is the Sennheiser HDB 630 worth the upgrade from the Shure Srh840a?
Verdict
Clear upgrade
Going from the Shure Srh840a to the Sennheiser HDB 630 buys you 14.0 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in sound (8.0 to 9.4) and value (7.5 to 8.4). On paper: active noise cancelling, driver size 40 mm to 42 mm and usb-c. Worth checking: weight goes 273 g to 311 g. That costs $281 more, or about $20 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.
