Our Verdict
Nothing Ear
CMF Buds Pro 2
The Nothing Ear are more upscale than the CMF Buds Pro 2, though their shared parent company means many features, including the app, are the same. The Nothing boast a more balanced sound signature by default with a more in-depth graphic equalizer for tinkerers. Their battery life is slightly longer, and they're slightly better built, too. On the other hand, the CMF offer a bit more powerful noise isolation overall. Other differences are dependent on taste, such as pinch controls on the Nothing or touch controls on the CMF.
