CMF Speaker S and M: 10W/35W Milk-Carton | IP68 | 18-Hour Battery

Sometimes the best gadget is the one you never have to think about. You drop it in a tote, carry it to a park bench, a kitchen counter, or a hotel bathroom, and it just plays. That’s the idea behind the CMF Speaker S — a compact portable Bluetooth speaker that leans on battery life and toughness instead of flashy extras.

A Milk Carton That Can Take a Dunking

The shape is the first thing people notice: it’s modeled after a milk carton, and that’s a genuinely practical choice. Tall, narrow footprints sit better on crowded counters and slip into side pockets more easily than wide, flat bricks. More importantly, this thing carries an IP68 rating, so it’s both waterproof and dustproof. Poolside, beach, shower shelf — the CMF Speaker S is built for places where electronics usually aren’t welcome.

What the Spec Sheet Actually Tells You

• Output power: 10 W
• Driver: single full-range driver
• Battery life: up to 18 hours
• IP rating: IP68 (waterproof and dustproof)
• Bluetooth: version 5.3
• Charging: USB Type-C
• App support: Nothing X app

That Bluetooth 5.3 spec matters more than it sounds — newer versions tend to hold a steadier connection and go easier on battery. And the USB Type-C port means one less cable to keep track of.

Where It Quietly Wins

Eighteen hours of playtime is the headline here. Real talk: plenty of small speakers in this class tap out well before that, so if you’re the type who forgets to charge things, this is a meaningful difference. Who actually wants to babysit a charger on a weekend trip? The Nothing X app also gives you a way to adjust the sound without touching the speaker itself, which is handy when it’s sitting across the room. And the color range — Light Grey, Dark Grey, and Orange — adds a little personality without costing you anything extra.

For what it’s worth, the 10 W full-range driver is a sensible match for a speaker this size. You’re not buying it for chest-thumping bass; you’re buying it for clear, even sound that fills a room or a picnic blanket.

Two Things Worth Checking First

Here’s the thing — the product title also mentions a “CMF Speaker M” with a 35 W dual-driver architecture. That’s a different model, and it’s easy to skim past. If the dual-driver version is what you’re after, make sure you’re actually selecting it; the CMF Speaker S is the 10 W single full-range driver unit.

The second catch is simpler: the listing doesn’t spell out the exact weight, so if pocket portability is your priority, it may be worth confirming with the seller before ordering.

If you want a small speaker you can leave in the rain, rinse off, and forget about charging for a couple of days, the CMF Speaker S makes a lot of sense. Have a look at the color options and see which one fits your setup.
