The CMF Buds Pro 2 use an in-ear fit and are fully wireless, with no neckband or cables involved. They weigh 9.8 g and carry an IP55 rating, meaning they offer resistance to both dust ingress and water splashes. Stereo playback is supported across both earbuds, while the design omits wingtips, RGB lighting, a UV light, and any built-in display, keeping the form factor straightforward and uncluttered.
The CMF Buds Pro 2 handle noise reduction on two fronts, combining active noise cancellation (ANC) with passive noise isolation. Audio is driven by an 11 mm neodymium magnet driver covering a frequency range of 20 Hz to 40,000 Hz, and spatial audio is supported. Dolby Atmos and Dirac Virtuo are not included.
Each earbud houses a 60 mAh rechargeable battery delivering up to 7 hours of playback, which drops slightly to 6.5 hours when ANC is active. The charging case carries a 460 mAh cell that extends total listening time to 36 hours combined, and a full charge takes 1.5 hours. A battery level indicator is present, while wireless charging and solar charging are not supported.
The CMF Buds Pro 2 connect wirelessly via Bluetooth 5.3 with a maximum range of 10 m and an audio latency of 120 ms. Supported codecs include LDAC and AAC, while aptX in all its variants (aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, aptX Voice) and LDHC are not supported. Fast pairing is available, and the case charges over USB-C, though NFC pairing is absent. Bluetooth LE Audio and Auracast are not included.
The CMF Buds Pro 2 include a practical set of features for daily use. Multipoint connectivity supports simultaneous pairing with two devices, and in-ear detection automatically pauses playback when the earbuds are removed. Ambient sound mode lets external audio pass through when needed, and a mute function is available during calls, as the earbuds can also serve as a headset. Fast charging is supported, and a find-device feature helps locate misplaced earbuds. Controls are handled via a panel on the device itself, and voice prompts are present, while an in-line control panel is not included. A travel bag comes in the box, though a built-in translator, body temperature sensor, remote shutter, and notification reading are all absent.
The CMF Buds Pro 2 feature a six-microphone array with noise cancellation, helping to reduce background noise during calls and voice input.
