CMF's $59 and $109 speakers differ mainly in drivers and weight
CMF's first Bluetooth speakers, the $59 S and $109 M, are on sale now with the same 18-hour battery rating. The software features match across the pair, so the $50 gap pays for a second driver and 270 extra grams.
The Product Desk
Key figures: the Speaker M weighs 270 grams more than the Speaker S; the M has a 25W woofer; the S has a 45mm full-range driver; both speakers offer up to 18 hours of battery life.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Extra weight of the Speaker M over the Speaker S | 270 g | 23 | |
| Speaker M woofer | 25 W | 4 | |
| Speaker S full-range driver | 45 mm | 2 | |
| Battery life, both speakers | 18 hours, up to | 6 |
What happened
- The S has a custom-tuned 45mm full-range driver with two passive radiators, while the M has a 10W tweeter and a dedicated 25W woofer.
- The S weighs 334g and the M weighs 604g.
- Both speakers can sync to other speakers, including other companies' models, through an Auracast-based party mode.
- CMF says both models adjust EQ in real time with AI and add an "Ultra Bass" mode for the low end.
- These are the first portable Bluetooth speakers from CMF, a budget brand Nothing created and is spinning off as an India-based subsidiary.
Why it matters
- Who has to decide decision A buyer who wants left and right channels has to pick a size before the second speaker exists, because stereo pairing works only between two S or two M.
- What doesn't add up contradiction Gizmodo says 3D-printing fans can print their own knobs, but The Verge says CMF only plans to release the design file, so printed parts depend on a release not yet made.
- What it costs cost CMF pitches the S as the grab-and-go model, so anyone who carries the M out of the house hauls an extra 270g.

A buyer comparing the two product pages finds few rows that differ. Past the AI EQ [9], both speakers carry an IP68 rating [24], EQ presets and custom profiles in the Nothing X app [10], and a multifunction knob and front panel that come off for swapping [3]. None of that helps a buyer choose between the S and the M.
Price and weight scale together. The M weighs 1.81 times what the S does [21] and costs 1.85 times as much [14].
Battery is the odd one. Gizmodo found it surprising that the larger M matches the S, at a maximum of 18 hours on both [5]. The Verge lists the figure as "up to" 18 hours [6]. Neither outlet reports the volume or test conditions behind it.
Sound is also untested in the coverage. Gizmodo's writer expects "a fairly drastic difference in the sound between the two, but it's hard to know for sure until you hear for yourself" [25]. Gizmodo also said it had asked CMF what the knobs cost and how many options exist, and that it would update its post [26].
We would start a first-time buyer on the S. It costs $50 less [15], and the sources list no feature the M has that the S lacks apart from its drivers and size [2]. The tradeoff is bass. The S has one 45mm driver and two passive radiators, and The Verge describes the M's dedicated woofer as the part for improved bass performance and better separation of instruments and singers [4].
Two axes sort the decision: whether the speaker leaves the house, and whether there will ever be two of them. A single speaker that travels is the S at $59 [1]. A single speaker that stays in one room is the M at $109 [1]. A traveling pair is two S at $118 [16], and a fixed pair is two M at $218 [17]. The pair box is where the sizes overlap: two S cost $9 more than one M [18] and weigh 668g against the M's 604g [22].
What to watch
- Gizmodo's promised update on what CMF charges for replacement knobs and how many options exist.
- Whether CMF publishes the official design file for 3D-printed knobs and panels, and when.
- Hands-on tests of the 18-hour battery rating and of how far apart the S and M sound.
