Is the Nothing CMF Buds 2a worth the upgrade from the Nothing CMF Buds Neo?
Verdict
Downgrade
The Nothing CMF Buds 2a actually scores 10.2 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 7.5) and calls (7.8 to 6.4). On paper it adds water resistance (IP54). Worth checking: battery life goes 11 h to 8 h and battery incl. case goes 52 h to 35.5 h. The two sit at effectively the same price. 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.
