Sound for all
CMF Buds 2a are designed to bring clear sound to all. With deep bass, active noise cancellation, and a secure, comfortable fit, they’re perfect for all-day listening.

Silence distractions
Block out background noise with 42 dB Active Noise Cancellation and a wide-band frequency range of up to 2900 Hz that filters everything from deep rumbles to everyday chatter. Transparency Mode lets in external sound without removing your buds. Four high-definition microphones with Clear Voice Technology isolate your voice from background noise, while Wind Noise Reduction 2.0 cuts wind interference for clear calls anywhere.

All-day battery and fast charging
Up to 8 hours of playback on a single charge, extending to 35.5 hours with the case. A quick 10-minute charge delivers 5.5 hours of listening with ANC turned off, keeping your music going when you need it most.

Protected for everyday use
IP54-rated for water and dust resistance. Built to handle splashes, dust and daily wear, ensuring your sound stays uninterrupted, whether you're caught in the rain or pushing through an intense workout.

Deep bass and crystal-clear highs
A custom 12.4 mm Bio-fibre driver works together with Dirac™-tuned audio and Ultra Bass Technology 2.0 to deliver immersive bass, rich mids and crystal-clear highs. For fuller, more balanced sound with every listen.

Functional by design
Lightweight and ergonomic, with a matte and glossy finish. Designed with a secure fit for all-day comfort. The case features a lanyard hole so you can take your sound anywhere.
