Is the Sennheiser HDB 630 worth the upgrade from the HiFiMAN HE 6?
Verdict
Clear upgrade
Going from the HiFiMAN HE 6 to the Sennheiser HDB 630 buys you 15.3 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in value (6.0 to 7.5) and sound (8.5 to 9.0). On paper: active noise cancelling and weight 502 g to 311 g. Worth checking: driver size goes 60 mm to 42 mm. It's also $849 cheaper, which makes this an easy call. 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.

About this verdict
Direction matters here: this page answers "HE 6 to HDB 630". 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.
