Sound that stuns — even at this size

Don't let its size fool you. Muo packs over 60 years of KEF acoustic innovation and expertise into a portable speaker that delivers room-filling sound, powerful bass, and crisp, detailed highs—wherever you are.

High-fidelity sound, everywhere

Powered by a large racetrack driver, P-Flex Surround technology, and a dedicated tweeter, Muo delivers accurate bass, smooth mids, and sparkling treble, even at high volumes. KEF’s Music Integrity Engine® ensures pristine sound quality with dynamic bass and remarkable clarity.

Always ready to play

Enjoy up to 24 hours of non-stop music on a singel charge. A quick 15-minute boost gives you 3 hours of playback, and a full charge takes just 2 hours.

Built to go where you go

With IP67 waterproof and dustproof protection, Muo is tough enough for rain, sand, and spills. It's engineered to perform in extreme temperatures from -20°C to 45°C. The included carrying strap makes it easy to grab, hang, and take anywhere.

Connect and Pair with Ease

Pair instantly with Google Fast Pair or Microsoft Swift Pair, or connect directly via USB-C. Take crystal-clear calls with the built-in noise-cancelling mic. For bigger sound, link two speakers for true stereo or multiple Muo speakers via Auracast™. Fine-tune settings with the KEF Connect app.

Better for the planet

Crafted using recycled plastics from bottles. appliances, and even old electronics, Muo combines sustainability with signature KEF sound.
