Is the Nothing CMF Buds 2a worth the upgrade from the SoundPEATS H3?
Verdict
Downgrade
The Nothing CMF Buds 2a actually scores 9.6 points below the SoundPEATS H3, so on aggregate review consensus this is a step backwards. The gains are concentrated in battery (5.3 to 7.5) and calls (5.6 to 6.4). You do give up ground on sound (9.0 to 7.0) and noise cancelling (8.1 to 6.8). Worth checking: codecs goes SBC, AAC, aptX, aptX Adaptive, aptX Lossless, LDAC to SBC, AAC and full charge time goes 60 min to 89 min. It is at least $104 cheaper, so the lower score comes with a saving. 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.
