Is the HiFiMAN HE 6 worth the upgrade from the Sennheiser HDB 630?
Verdict
Downgrade
The HiFiMAN HE 6 actually scores 15.3 points below the Sennheiser HDB 630, so on aggregate review consensus this is a step backwards. It loses ground on value (7.5 to 6.0) and sound (9.0 to 8.5). On paper: driver size 42 mm to 60 mm. Worth checking: active noise cancelling goes Yes to No and weight goes 311 g to 502 g. And it costs $849 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 "HDB 630 to HE 6". 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.
