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.

Muo stays in step with your rhythm. Bluetooth® 5.4 aptX Adaptive™ keeps every note perfectly in sync, while the 24-hour 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 KC62 and KC92 subwoofers, 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.
