Our Verdict
Nothing Ear (2)
CMF Buds Pro 2
The Nothing Ear (2) belong to a previous generation of earbuds with less powerful ANC than the CMF Buds Pro 2. That said, the Nothing have a more comprehensive equalizer and a flatter sound profile. They're better made and use pinch controls. Still, the CMF use the same app as the Nothing, albeit with a slightly pared-back version with a simpler EQ. They're bassier by default and have a slightly longer continuous battery life. However, their touch controls are a bit less reliable than the Nothing.
