Our Verdict

CMF Buds Pro 2

Nothing Ear (3a)

The Nothing Ear (3a) and CMF Buds Pro 2 are close relatives: both are part of the same parent company, and they both ship with bass-heavy tunings and comparable battery lives. But the Nothing are the better earbuds. They're more comfortable, use pinch controls that respond more reliably, and offer a more detailed parametric EQ in their companion app. Still, the CMF record speech more naturally in quieter conditions and have a distinctive case dial for controlling playback and volume, but their touch controls occasionally misread inputs.
