CMF’s first reported speakers, the Speaker S and Speaker M, have a milk-carton-inspired shape and a prominent control knob. Early retailer listings describe their designs and some specifications, but they do not confirm that the knob is interchangeable. The pair was scheduled to be revealed on October 12, 2026; the details available ahead of that date should be treated as provisional.
What are CMF Speaker S and Speaker M?
CMF by Nothing’s first reported portable speakers are called Speaker S and Speaker M. Reporting on FCC filings identifies them as portable wireless speakers with model numbers E494 and E495, respectively. The scheduled reveal date was October 12, 2026, according to Gizmochina and Droid Life.
The speakers would broaden CMF’s product range beyond its 2023 debut lineup: Buds Pro, Watch Pro, and Power 65W GaN, announced by CMF through PR Newswire.

Early retailer imagery described in the reports shows each speaker with a gable-top enclosure—the peaked shape associated with a milk carton—and an integrated carry handle. The Speaker S has one front grille; the Speaker M has two. Those visible differences distinguish the designs, but they do not by themselves establish a difference in sound quality or performance.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Does either speaker have swappable buttons?
Not confirmed. The coverage describes a physical control knob, and a teaser reportedly suggested that it may be swappable. However, the retailer listings do not establish that the knob can be removed or replaced. The available descriptions support “knob,” not interchangeable buttons or a confirmed accessory system. Until CMF confirms the mechanism, treat swappability as a possibility rather than a feature.
What specifications have been reported?

These are retailer-reported details, not independently verified measurements. In particular, “up to 18 hours” is a listing claim; the reports do not specify test conditions such as volume level or playback content. The available information also does not establish final dimensions, regional prices, or a complete comparison of the two models.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What should buyers check before deciding?
- Look for CMF’s official announcement and final specifications rather than assuming every pre-launch listing detail is final.
- Check the price and availability for your region, and confirm the seller and exact model before ordering.
- Do not count on a replaceable knob or compatible alternate control unless CMF confirms it.
- Compare final dimensions, weight, driver configuration, output, battery claims, and water and dust resistance once CMF publishes comparable details for both speakers.
The reports do not establish a confirmed regional Amazon listing. The scheduled reveal date alone should not be taken as proof of current availability or a live purchase listing.
