The CMF Speaker M is the bigger half of CMF by Nothing’s milk carton speaker line: a tall, geometric body with swappable panels and a built-in handle. A 70 mm woofer and 16 mm tweeter split 35 W RMS between them for a 60 Hz–20 kHz range, a clear step up from the compact Speaker S. It keeps the family traits — Bluetooth 6.0, NFC pairing, USB-C lossless audio, Auracast, IP68 sealing and up to 18 hours of playback — in a speaker meant to fill a room rather than a desk corner.
