Muo reimagines portable audio. Designed to move you with every moment, it’s compact enough to fit into your bag and powerful enough to fill a room with rich, layered audio that defies expectations. Designed by Ross Lovegrove, Muo translates the sculptural ambition of our iconic Muon speakers into a portable masterpiece.

KEF Muo Speaker Review: Style Meets Sound in the New Portable Bluetooth Speaker

Audio specialist KEF has just unveiled its refreshed portable speaker, the Muo, reimagined to blend premium hi-fi performance with real-world versatility. Drawing from KEF’s elite loudspeaker heritage, this latest Muo is aimed at those who refuse to compromise sound quality while on the move.

What’s New & Why It Matters

  • The new Muo employs a racetrack-shaped mid/low driver paired with a dedicated dome tweeter, delivering deeper bass and clearer highs compared to most compact portable speakers.

  • KEF has integrated its P-Flex surround technology, used in its flagship subwoofers, to reduce distortion and enhance bass control within the compact enclosure.

  • Built-in sensors automatically optimize the sound for upright or horizontal orientation.

  • Connectivity includes Bluetooth 5.4 with aptX Adaptive, USB-C wired playback, and fast pairing via Google Fast Pair and Microsoft Swift Pair.

  • The design emphasizes durability with an IP67 water- and dust-resistant rating, and battery life rated for up to 24 hours, with a 15-minute quick charge providing roughly 3 hours of playback.

  • The Muo is available in seven finishes — Silver Dusk, Amber Haze, Orange Moon, Blue Aura, Moss Green, Cocoa Brown, and Midnight Black — all featuring sculptural styling by designer Ross Lovegrove, inspired by KEF’s iconic Muon loudspeakers.

  • Sustainability has been addressed through the use of post-consumer recycled materials in the speaker’s construction.

For audio enthusiasts, the new Muo stands out by bringing many hallmarks of KEF’s hi-fi engineering into a portable format. Its extended low-end reach, sculpted design, and refined acoustic balance make it a rare example of a travel-friendly speaker that still prioritizes fidelity. The IP67 rating and long battery life also make it genuinely practical for outdoor or travel use.

Amongst it's competitors in this field, it sits in the premium end of the portable Bluetooth market — pricier than mainstream models but offering a more sophisticated sonic signature. For those who value clarity, craftsmanship, and design excellence, the new KEF Muo is an impressive and distinctive choice.
