Is the HiFiMAN HE 600 worth the upgrade from the Nothing CMF Headphone Pro?
Verdict
Downgrade
The HiFiMAN HE 600 actually scores 9.6 points below the Nothing CMF Headphone Pro, so on aggregate review consensus this is a step backwards. It loses ground on value (9.0 to 7.5). On paper: driver size 40 mm to 100 mm. Worth checking: active noise cancelling goes Yes to No and weight goes 283 g to 389 g. One caution: this steps down a line tier (CMF Headphone Pro to HE 600), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. And it costs $720 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 "CMF Headphone Pro to HE 600". 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.
