CMF Speaker S and M: Bluetooth Speakers Shaped Like Milk Cartons

What this means for you

If you want an affordable, water-resistant Bluetooth speaker that looks different from the usual tubes and cans, both models are worth comparing.

Two speakers, two uses

The S is the grab-and-go model. It weighs 334 grams (about 12 ounces), measures 5.1 by 3.3 by 1.7 inches, and uses a single 1.8-inch driver with two passive radiators.

Terms you'll see on the spec sheet

Auracast is a Bluetooth feature that broadcasts the same audio to many compatible speakers or headphones without pairing each one.

A design you can change

The look follows a milk carton's geometry. Yanko Design traces the shape to John Van Wormer's 1915 Pure-Pak patent, which he filed in Toledo, Ohio.

Price and availability

The speakers went on sale October 12 at nothing.tech and select retailers. In the US the S costs $59 and the M costs $109.

Are they worth it?

On paper, the pitch is strong for the money: IP68 protection and 18 hours of battery in a $59 speaker is uncommon.
