KEF Muo Portable Bluetooth Speaker

Muo reimagines portable audio, encapsulating high fidelity sound in a design made for life on the move. Compact enough to slip into your bag yet powerful enough to fill a room, it delivers rich, layered audio that defies expectations. Every note feels alive: bass with weight you can feel, clarity that reveals forgotten lyrics, and a richness that turns playlists into immersive experiences.

KEF Muo Portable Bluetooth Speaker

Muo stays in step with your rhythm. Bluetooth® 5.4 aptX Adaptive™ keeps every note perfectly in sync, while the 24-hour1 battery carries you from morning coffee to late-night unwinding. Take calls in crisp clarity with the built-in microphone, and let the IP67-rated build shrug off downpours, dust, or the chaos of everyday life. Your vibe? Unstoppable.

But Muo isn’t just heard—it’s seen. Designed by renowned industrial designer Ross Lovegrove, its sculpted silhouette draws inspiration from the iconic Muon HiFi speakers. Crafted for those who demand excellence, Muo translates Muon’s sculptural ambition into a portable icon —making a statement as striking as its sound.

High fidelity sound that stuns—even at this size

Get ready to be amazed the moment you hit play. Drawing on over 60 years of acoustic innovation—with no compromises—we've distilled our award-winning speaker expertise into this portable design. Muo delivers powerful bass, crisp details, and room-filling sound, all while defying expectations of what portable audio can achieve.

A highly efficient dedicated racetrack driver has been specifically developed for Muo. With its long excursion and large cone area, it allows Muo to reproduce the lower notes in the bass register with low distortion and low power consumption. The result is a delivery of impressive output and deep controlled bass that punches above its weight whilst ensuring long playback times. Drawing from experience with KEF’s award-winning small and powerful subwoofers KC62 and KC92, P-Flex Technology has been incorporated into the bass driver’s surround, which resists deformation otherwise caused by high internal air pressure from the small enclosure; thus avoiding distortion and ensuring a clean bass delivery.

A new dedicated 19mm dome tweeter further improves the high-frequency performance that is characteristic of Muo, conveying a natural and clear reproduction of every musical detail in any listening situation.

Muo incorporates the latest Music Integrity Engine® (MIE), KEF’s proprietary suite of advanced DSP algorithms developed for KEF’s larger range of HiFi speakers, such as LS60 Wireless. MIE dynamically adapts the music signal to unleash deep bass extension from a small speaker like Muo whilst ensuring control and clarity at all listening levels with any kind of musical content.

With Bluetooth® 5.4 aptX Adaptive™, Muo offers high-fidelity, low-latency audio for seamless listening, delivering exceptional clarity and a reliable connection wherever you go.

Always ready, anywhere

Life doesn’t pause—neither does your music. Muo powers through up to 24 hours1 of playback, carrying you from morning to night and beyond. Short on time? A 15-minute quick charge provides up to 3 hours1 of listening, with a full recharge in just 2 hours—so power is never the reason your music stops.

Engineered for the unpredictable, Muo's IP67-rated waterproof and dustproof design protects against rain, sand, and spills, and whatever else life throws your way. With an operating range of -20°C to 45°C, Muo is ready to perform in any climate—whether in freezing winters or scorching heatwaves, ensuring the fun never stops.

The carrying strap makes portability effortless. Grab it, carry it, or hang it in your favourite spot. Wherever you go, Muo follows with seamless ease.

Adapts to your every need

Life moves fast, Muo keeps up. This versatile portable speaker seamlessly integrates into your day, whether for focused work or lively gatherings. Connect effortlessly with Google Fast Pair and Microsoft Swift Pair—a single tap is all it takes. A USB Type-C port offers a simple wired connection to your laptop.

Let your voice be heard, with clarity. The built-in microphone with noise and echo cancellation ensures every word is captured during your calls and catch-ups.

For a truly immersive audio experience, pair two Muo speakers as they awaken into a portable stereo HiFi system—dedicated left and right channels working in harmony to deliver true wireless stereo sound with pristine detail, dimensional depth, and precise spatial imaging. You can also amplify the audio impact by linking multiple Muo speakers via Auracast™2 , elevating the energy of parties, letting everyone immerse themselves in your curated playlist.

The KEF Connect App puts control at your fingertips. It allows you to manage speaker settings and update firmware, making it easy to control the Muo from a single, intuitive interface.

Design that resonates with you

More than a speaker, Muo is an emotional statement. Designed by Ross Lovegrove, Muo inherits the striking DNA of KEF's flagship Muon HiFi speakers, blending exceptional acoustic engineering with iconic form. Now distilled into a portable form with its iconic silhouette, Muo brings the essence of a HiFi masterpiece into everyday life.

However you like it, wherever you need it, Muo adapts. Its EQ auto-optimises output to suit its orientation, whether standing up or lying down, Muo delivers the same outstanding acoustic depth and definition.

Available in seven vibrant finishes with tone-on-tone carrying straps, including Silver Dusk, Amber Haze, Orange Moon, Blue Aura, Moss Green, Cocoa Brown, and Midnight Black, Muo is crafted from premium aluminium, adding a touch of elegance and sophistication to your everyday life, making it uniquely yours.
