CMF Speaker S and M launch with USB-C audio and distinct stereo options

CMF's first portable speakers offer two ways to size the same listening setup: the lighter Speaker S for carrying, and Speaker M with a separate woofer and tweeter. Their more useful distinction from a basic Bluetooth speaker is how they can connect. A wired desk setup, a left/right stereo pair and music shared across several speakers require different arrangements.

Nothing's official launch post is dated October 12, 2026. The story was discovered through The Verge's October 8 report; the product details here come from Nothing's announcement and specifications, rather than independent listening tests.

Pick the size before the interchangeable panels

The Speaker S specifications list a 334 g enclosure and one 45 mm full-range driver, with 10 W RMS output. The Speaker M page lists 602 g and a 70 mm woofer plus 16 mm tweeter, with 35 W RMS combined output.

The S is therefore the lighter item to carry. The M divides low and high frequencies between drivers, giving it a different acoustic design. The output numbers alone cannot establish perceived loudness, distortion or whether either speaker sounds better in your room. Those questions need listening or measurements under comparable conditions.

Stereo and Party Mode serve different jobs

Nothing documents stereo pairing between two identical models: two S units or two M units produce separate left and right channels. Buying one of each should not be treated as a documented stereo configuration.

Party Mode instead uses Auracast to share playback with compatible speakers, including compatible devices from other brands. That is useful when coverage across a gathering matters; compatibility still needs checking for the particular other speaker. It is a different goal from separating the channels at a desk.

Both models also accept USB-C audio. Nothing claims latency below 60 ms on that connection, while its Bluetooth footnotes report higher figures that depend on codec and mode. A laptop user interested in video or games should evaluate the wired path first, then check the actual source device and application. These manufacturer measurements do not prove end-to-end delay in every setup.

Customization needs careful reassembly

The front panel and volume knob are removable, and Nothing has published a 3D-printing guide. This gives owners a way to change the exterior without replacing the speaker. The M's instructions warn that an incorrectly reinstalled front panel can affect acoustic performance or other functions; customization is not evidence that internal repairs are user-serviceable.

Nothing's up-to-18-hour playback claim uses 50% volume, AAC, Balanced EQ and Ultra Bass enabled in laboratory conditions. Higher listening levels and different conditions can change that result. If your current speaker already handles the intended connection and room, these additions alone do not justify replacing it. Prospective buyers should wait for comparable listening evidence if sound quality is the deciding factor.
