Our Verdict
Anker Soundcore P40i
CMF Buds Pro 2
The CMF Buds Pro 2 and the Anker Soundcore P40i are both affordable ANC earbuds with different strengths and weaknesses. Both are bassy, but the CMF sound a bit more balanced with a warmer treble, while the Anker have a much more excited sound profile. You can EQ either. The CMF have a more accurate-sounding microphone system that filters out background noise a bit better. They also let you use the LDAC codec for Hi-Res audio files. Meanwhile, the Anker boast a longer continuous battery life and a lower latency performance. The Anker also feel a little more comfortable with more ear tips to find your fit.
