CMF by Nothing unveils modular, milk carton-styled portable speakers

Organisations monitoring consumer electronics trends should note the launch of CMF by Nothing’s first portable speakers, which prioritise modular design over traditional aesthetics. According to TechRadar, the Speaker S and Speaker M models feature a distinctive milk carton-inspired shape that allows users to detach the outer panels. This design choice enables owners to 3D print their own replacement covers, offering a level of physical customisation rarely seen in mass-market audio hardware.

The sub-brand has positioned these devices as affordable entry-level options, with the compact Speaker S priced at £49 ($59) and the larger Speaker M at £99 ($109). Both units are available in white, dark grey, orange and turquoise. While the visual presentation is unconventional, the technical specifications align with current market standards for portable Bluetooth audio, focusing on connectivity range and battery efficiency rather than high-fidelity studio reproduction.

What we know

The Speaker S is engineered for portability, housing a custom-tuned 45mm driver alongside two passive radiators to enhance bass response in a smaller form factor. In contrast, the Speaker M targets users requiring greater room-filling audio, supporting a frequency range of 60Hz to 20kHz. Despite the size disparity, both devices share core functional features, including 18 hours of playback at 50% volume with Ultra Bass enabled.

Connectivity is a central feature for both models, which support Bluetooth 6.0. This standard provides a connection range exceeding 100 metres between the speaker and the source device. TechRadar notes that both speakers allow dual-device connection, enabling users to switch audio sources without re-pairing. This functionality is designed for scenarios where multiple users may wish to control playback sequentially.

Battery management includes a fast-charging capability, where ten minutes of charging provides one hour of playback. For users seeking a more immersive experience, CMF offers Stereo Mode, which allows two Speaker S or Speaker M units to be paired as left and right channels. This creates a stereo soundstage from two separate devices, expanding the audio footprint beyond a single mono source.

Defender's checklist

• Verify that Bluetooth 6.0 firmware is up to date on all connected source devices to ensure stable pairing.
• Inspect detachable panels for structural integrity before shipping or transporting the devices to prevent loss.
• Monitor battery health indicators regularly, as fast-charging cycles can impact long-term lithium-ion performance.
• Confirm that dual-device connection settings are configured correctly to prevent audio interruption during handovers.

What to do and how to stay safe: CMF by Nothing

• Review your organisation’s acceptable use policy regarding personal Bluetooth audio devices in secure or quiet workspaces.
• Ensure that employees understand how to manage dual-device connections to prevent accidental audio broadcasting from personal devices.
• Check that any 3D printed accessories do not interfere with the speaker’s ventilation or driver components.
• Once the vendor provides an update, apply firmware patches to maintain Bluetooth security protocols and connectivity stability.
