Is the Nothing CMF Buds Neo worth the upgrade from the Nothing CMF Buds 2a?
Verdict
Clear upgrade
Going from the Nothing CMF Buds 2a to the Nothing CMF Buds Neo buys you 10.2 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. 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. If your current pair is worn out or the gains line up with how you listen, this one is worth the money.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
