Is the Nothing CMF Buds Neo worth the upgrade from the Nothing CMF Buds 2a?
Verdict
Meaningful upgrade
The Nothing CMF Buds Neo scores 9.8 points above the Nothing CMF Buds 2a. That's a real improvement, though not the kind you'd notice on every track. The gains are concentrated in battery (7.5 to 9.0), calls (6.4 to 7.8) and noise cancelling (6.8 to 7.8). On paper: battery life 8 h to 11 h, battery incl. case 35.5 h to 52 h and full charge time 89 min to 10 min. Worth checking: water resistance goes IP54 to Not rated. The two sit at effectively the same price. Worth doing if you're replacing anyway; harder to justify as a pure upgrade if what you have still works.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
