The CMF Buds is a pair of TWS earbuds that brings hybrid ANC rated up to 42 dB, a 12.4 mm bio-fibre driver and Bluetooth 5.3 with Dual Connection to everyday listening. It suits students and commuters on iPhone or Android who want Dirac-tuned sound and a lanyard-ready case.

Who the CMF Buds is for

  • Students: Dual Connection lets one pair stay linked to a phone and a laptop at once.
  • Daily commuters: Hybrid ANC rated up to 42 dB quiets buses and trains, and Transparency mode lets announcements through when you need them.
  • iPhone and Android users: Works with iOS 13+ and Android 5.1+ over AAC or SBC, and supports Google Fast Pair and Microsoft Swift Pair.
  • Style-minded listeners: Offered here in Black, White or Orange, with a rotating dial on the case that exposes a lanyard hole.
  • Skip it if: you want marathon sessions between case top-ups; the earbuds last up to 8 h with ANC off and 5.6 h with it on.
