Is the OnePlus Buds Z worth the upgrade from the Nothing CMF Buds Neo?
Verdict
Downgrade
The OnePlus Buds Z actually scores 30.2 points below the Nothing CMF Buds Neo, so on aggregate review consensus this is a step backwards. It loses ground on battery (9.0 to 4.3) and calls (7.8 to 5.0). On paper it adds water resistance (IP55). Worth checking: battery life goes 11 h to 5 h and active noise cancelling goes Yes to No. And it costs $28 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.
