Verdict

Marginal upgrade

There's only 4.6 points between the Nothing CMF Buds 2a and the Nothing CMF Buds 2. That's inside the range where two reviewers might simply disagree. The gains are concentrated in battery (7.0 to 8.0) and calls (6.5 to 7.0). You do give up ground on sound (8.0 to 7.5) and noise cancelling (7.5 to 7.0). On paper: battery life 8 h to 13.5 h, battery life (anc on) 5 h to 7.5 h and battery incl. case 35.5 h to 55 h. Worth checking: driver size goes 12.4 mm to 11 mm. That costs $16 more, or about $3 per point of score - reasonable value for the jump. Keep what you have unless a specific feature above is the thing you're missing - the overall quality gap won't be what convinces you.
