CMF Speaker S

CMF, Nothing's affordable technology brand, has released STL design files so owners can 3D-print their own panels, knobs and other parts for its first portable Bluetooth speakers, the Speaker S and Speaker M.

Both are built around a milk carton-inspired body with removable front panels and multifunction control knobs. The two differ in size and drivers. The Speaker S measures 130.5 × 85 × 44mm, weighs 334 grams and has a 45mm full-range driver rated at 10W RMS, backed by two passive radiators. The Speaker M measures 220 × 85 × 54mm, weighs 602 grams, and splits the work between a 70mm woofer at 25W RMS and a 16mm tweeter at 10W RMS, 35W RMS combined.

Connection is shared across the pair. Bluetooth 6.0, NFC pairing, Google Fast Pair and Microsoft Swift Pair are supported, and two devices can stay connected at once. USB-C audio is supported too, with Nothing claiming latency below 60 milliseconds. Party Mode uses Auracast to share audio with other compatible speakers, while Stereo Mode pairs two of the same model as left and right channels.

CMF advertises up to 18 hours of playback on both, measured at 50% volume with AAC audio, Balanced EQ and Ultra Bass. The Speaker S has a 2,600mAh battery that recharges in about 2.5 hours, and the Speaker M has a 4,900mAh battery that takes about three. Both carry an IP68 rating, specified for freshwater immersion up to 1.5 metres for 30 minutes under controlled conditions, and the Nothing X app adds Balanced, More Bass, More Treble and Voice presets alongside Custom EQ and Night Mode.
