CMF Buds Pro 2 look like plenty of other true wireless earbuds but they have a few features that make them stand out. The most noticeable is a Smart Dial on the charging case. The dial can be turned, pressed and double-clicked to do a variety of things. It can be used as a volume control, a switch for turning on Noise Canceling or for simply pausing the music. The Smart Dial is fully programmable using the CMF smartphone app. The CFM Buds Pro 2 have a frequency response from 20Hz to 40kHz, making them eligible for Hi-Res Audio certification. Most earbuds go up to 20kHz, but these go further. Whether your ears are good enough to hear that high a frequency is open to question, but the overall range does have an impact on the music.
