KEF Muo: Premium Bluetooth Speaker Challenging Sonos Roam’s Reign

Experience premium sound with KEF Muo, the Bluetooth speaker boasting top-tier features and a bold price tag that sparks debate.

The Exciting New Contender in Portable Audio

If you're a fan of portable Bluetooth speakers, you’ll want to hear about KEF’s latest offering: the KEF Muo Bluetooth Speaker. Priced at $249 / £249, this new generation of KEF’s Muo promises a powerful auditory punch wrapped in a sleek, eco-conscious design. Sporting Bluetooth 5.4 with Auracast and aptX Adaptive, along with a robust 40W amplifier and an impressive 24-hour battery life, this speaker aims to shake up the portable audio market.

KEF has long been known for its commitment to sound quality and design, and the Muo continues that tradition. Designed by the renowned Ross Lovegrove—the same visionary behind the iconic KEF Muon speakers—the Muo retains its distinct, vibrant style. What's even cooler is that it now uses extensively recycled plastics, dialing down environmental impact without compromising on aesthetics or durability.

Engineering a Richer Sound Experience

At the heart of the KEF Muo Bluetooth Speaker is a specially engineered “racetrack”-shaped driver—an oval rather than a traditional round design. This unique shape is key to delivering powerful bass without distortion or excessive power drain, making it a rare feat in a compact speaker.

Adding to its sonic arsenal, KEF’s P-Flex technology—which we’ve seen in their KC62 and KC92 subwoofers—helps counteract driver deformation caused by internal air pressure. The result? Clean, punchy bass that doesn’t muddy the mids or highs. Supporting this is a new 19mm dome tweeter, designed to elevate treble clarity and detail.

Muo can also be paired with another unit to create a true stereo soundstage or linked to multiple speakers using Auracast technology for a wider listening setup.

Small Size, Big Sound

Inside the Muo, two Class-D amplifiers work their magic: a 10W amp for highs and a 30W amp for lows. This configuration yields a frequency response range from a respectable 43Hz up to 20kHz, covering the essentials for most music genres.

The speaker’s hardware is further enhanced by KEF’s Music Integrity Engine—a suite of proprietary algorithms crafted to optimize audio quality and enrich detail. Whether you want to build a stereo pair or multi-room setup with Auracast, the Muo has you covered.

For connectivity, it supports USB-C for laptop connections and is compatible with Google Fast Pair and Microsoft Swift Pair, making device syncing smoother than ever. Plus, a built-in microphone lets you take crystal-clear voice calls on the go.

Built for Adventure and Style

Don’t worry about the elements—Muo comes with an IP67 rating, ensuring it’s water and dust resistant. It can operate comfortably in temperatures ranging from -20°C to +45°C (that’s about -4°F to 113°F for those of us thinking in Fahrenheit). The rechargeable battery offers up to 24 hours of continuous playback and can jump back to 3 hours of use after just a quick 15-minute charge.

Weighing in at 740 grams, it’s lightweight enough to bring anywhere. Plus, it comes in seven eye-catching colors, each with matching carrying straps to suit your vibe: Silver Dusk, Amber Haze, Orange Moon, Blue Aura, Moss Green, Cocoa Brown, and Midnight Black.

Comparing with the Sonos Roam: Is It Worth the Premium?

The triangular shape and speaker positioning of the Muo bear a striking resemblance to the second-generation Sonos Roam Portable Speaker. However, the KEF comes with a heftier price tag—$249 (about £249) versus the Sonos Roam’s $179 (£179). That’s quite a gap for a portable speaker, especially when Sonos is known for solid performance and ecosystem integration.

The big question is whether the Muo’s premium audio components, environmental initiatives, and tech features justify this difference. Fans of KEF’s rich sound signature and unique design might see the Muo as a worthy upgrade. As the saying goes: sometimes you pay for what you hear.

KEF Muo retains its distinct, vibrant style… using extensively recycled plastics, dialing down environmental impact without compromising on aesthetics or durability.
