CMF, the sub-brand of Nothing, has announced its first speaker lineup with two portable Bluetooth speakers, the CMF Speaker M and CMF Speaker S. Both speakers feature a customisable design, IP68 dust and water resistance, Bluetooth 6.0, and up to 18 hours of battery life. However, they differ in size, driver configuration, and audio output.
The CMF Speaker M is the more powerful model, with a dedicated woofer and tweeter delivering 35W RMS output. The smaller CMF Speaker S uses a 45mm full-range driver and delivers 10W RMS output. Both models are available in four colours: white, dark grey, turquoise, and orange.
The CMF Speaker M features a 70mm woofer and a 16mm tweeter, with separate drivers handling low and high frequencies. It delivers 35W RMS output, split between 25W for the woofer and 10W for the tweeter. Its frequency response ranges from 60Hz to 20kHz.
The CMF Speaker S is a more compact option with a 45mm full-range driver and two passive radiators to improve bass output. It delivers 10W RMS power and has a frequency response of 70Hz to 20kHz. The larger Speaker M should offer more powerful sound, while the Speaker S is designed for users who want a smaller and lighter speaker.
Both speakers support Ultra Bass mode, which boosts low-frequency output, and Wide Soundstage mode, which aims to create a wider sense of space when playing audio through a single speaker. They also offer adaptive tuning and custom equaliser settings, including Balanced, More Bass, More Treble, and Voice presets. Night Mode reduces power consumption and bass output, with maximum loudness limited to around 60% of Standard Mode.
Users can pair two identical Speaker M or Speaker S units in Stereo Mode to create separate left and right audio channels. Party Mode uses Auracast to synchronise playback across multiple compatible speakers, including supported models from other brands.
The CMF speakers feature a compact, upright design inspired by a milk carton. Their front panels and volume knobs can be removed using an unlock switch on the back, allowing users to customise the appearance. CMF also provides a guide for 3D-printing replacement panels and knobs.
Both models carry an IP68 rating for dust and water resistance. They are designed to withstand dust, sand, rain, and splashes, and can survive submersion in up to 1.5 metres of water for up to 30 minutes under specified test conditions.
CMF claims up to 18 hours of playback on both speakers with Ultra Bass enabled at 50% volume. The Speaker M packs a 4,900mAh battery, while the smaller Speaker S has a 2,600mAh battery.
Both speakers charge through USB Type-C at up to 15W. A full charge takes around three hours for the Speaker M and 2.5 hours for the Speaker S. A 10-minute charge can provide up to one hour of playback, according to the company.
Connectivity options include Bluetooth 6.0, NFC tap-to-pair, and dual-device connectivity, allowing two Bluetooth sources to remain connected. CMF claims a Bluetooth range of more than 100 metres in open space. The speakers also support Google Fast Pair, Microsoft Swift Pair, and quick pairing with compatible Nothing devices.
Both models support USB-C audio playback with latency below 60ms. They use AAC and SBC Bluetooth codecs, along with LC3 for Auracast audio.
CMF Speaker M and Speaker S price and availability
The CMF Speaker S costs USD 59, £49, or €59, while the CMF Speaker M is priced at USD 109, £99, or €99. Both models are available through the official Nothing website and select retail partners in white, dark grey, turquoise, and orange.
The Speaker S is the smaller and more affordable option, while the Speaker M costs more because it uses separate woofer and tweeter drivers and offers substantially higher output power. Both share most of the connectivity, customisation, and durability features, so the choice mainly comes down to size and the level of sound output users need.
