CMF by Nothing Speaker S-Portable Bluetooth Speaker

CMF Speaker S with portable sound and easy carry

CMF Speaker S is a compact Bluetooth speaker for buyers who want a speaker they can move around easily without giving up the basic controls and connectivity options that matter for daily listening.

Compact Build for Easy Carry

The speaker uses a small, portable form factor and includes a carabiner hook for easier carrying. That makes it more practical for desk use, moving between rooms, or taking along in a bag when you need music outside the home.

45 mm Driver Output

Nothing lists a 45 mm full-range driver with 10 W RMS output and two passive radiators. For shoppers, that tells you the speaker is built for personal listening rather than a large-room setup.

Bluetooth 6 and Dual Connection

The speaker supports Bluetooth 6 and dual device connection, so it can stay paired with two devices at once. That is useful if you switch between a phone and laptop during work, study, or entertainment.

USB-C Audio and Custom Sound

CMF Speaker S also supports USB-C audio playback, and Nothing X app features include EQ controls such as Balanced, More Bass, More Treble and Voice. The page also notes low-latency wired playback, which can matter for video or gaming use.

Battery and Fast Charging

Official support information lists up to 30 hours of playback with Ultra Bass off and 18 hours with Ultra Bass on, under the stated test conditions. The speaker also supports USB-C charging and a 10-minute charge can add around 1 hour of playback under the specified conditions.

What to Check Before Ordering

If you are comparing portable speakers, focus on the size, battery mode, and whether you want Bluetooth-only listening or the added option of USB-C audio. The model also offers IP68 dust and water protection, but buyers should still match that to their own use case before choosing.
