CMF Buds: ANC TWS earbuds with a 12.4 mm bio-fibre driver tuned with Dirac Opteo and hybrid noise cancelling up to 42 dB. A good first ANC pair for students and commuters: Dual Connection links a phone and laptop at once, and the case extends playback up to 35.5 hours (ANC off).
Who the CMF Buds is for
First-time ANC buyers: Hybrid ANC up to 42 dB, plus a Transparency mode, takes the edge off bus rides and open offices.
Students with a phone and a laptop: Dual Connection, switched on in the Nothing X app, keeps both devices linked at the same time.
Bass and EQ tinkerers: Ultra Bass Technology 2.0 sits alongside Dirac Opteo and five EQ presets: Rock, Electronic, Pop, Enhance Vocals and Classical.
Color fans: This listing comes in White or Orange, and the case's rotating dial reveals a lanyard hole for hands-free carrying.
Skip it if: you want LDAC or another hi-res codec, because the CMF Buds stream AAC and SBC only.
