KEF Muo Review | 130 Data compared

The TechRadar review of the second-generation KEF Muo (2025) highlights a handsome, well-crafted, and highly capable aptX Adaptive Bluetooth speaker featuring exceptional aluminum build quality, USB-C connectivity, and high-res codec support. While praising its design, the review notes drawbacks including a lack of Wi-Fi, limited app controls, and an over-prominent midrange that disrupts the sound signature.

The second-generation KEF Muo ($250) delivers an impressive portable hi-fi experience, justifying its premium cost with outstanding audio quality, a durable aluminum chassis with IP67 protection, 24-hour battery life, and high-res USB-C desktop capability. While offering advanced Bluetooth 5.4, the speaker lacks Wi-Fi, features limited app control, and has stiff physical buttons.

The KEF Muo is praised by What Hi-Fi? for delivering musical, clear, and articulated audio, successfully applying premium hi-fi engineering to a portable speaker with innovative orientation-sensitive drivers. While offering impressive performance, the speaker is limited by its small form factor, lacking the brute force needed for large rooms, and it does not include a 3.5mm cable.

The PCMag UK review of the KEF Muo highlights a stylish, aluminum-cased Bluetooth speaker capable of producing rich, clean audio with crisp highs and powerful volume for its size. While offering a 12-hour battery life and capable performance, the speaker is held back by a high $349.99 price point, intense vibration at maximum volume, a lack of speakerphone, and limited sub-bass response.

Rad Bennett’s review for SoundStageXperience praises the KEF Muo as a "Reviewers' Choice" portable speaker that delivers serious high-fidelity sound through two 2" Uni-Q drivers. While lauded for its exceptional, room-filling soundstage and solid build quality, the Muo's drawbacks include a high $349.99 price point, reliance on an older Micro-USB port, and a standard 3.5mm auxiliary input. SoundStage!

In The Absolute Sound's review, the KEF Muo wireless speaker is described as a portable, "tiny two-way" system featuring miniature versions of KEF's high-end Muon drivers. The speaker delivers impressive, expansive sound with good resolution and soundstaging for its size, but setting up a second unit for stereo mode requires a complex, multi-step button sequence.

The KEF Muo bluetooth speaker, designed by Ross Lovegrove, justifies its high price with exceptional audio performance, featuring a premium aluminum chassis and KEF’s signature Uni-Q driver technology for a balanced, immersive soundscape. Key strengths include an innovative orientation sensor for optimized sound, while the drawbacks are limited to its premium price tag, lack of high-level water resistance, and slightly heavy, less portable design.

The Audioholics review of the KEF Muo praises the portable Bluetooth speaker for its premium aluminum build, 12-hour battery life, and expansive, high-quality sound. While the speaker offers innovative wireless stereo pairing and orientation-sensing, the review notes a significant drawback in the glitchy pairing process, which requires resetting the connection whenever the units are powered off. Additionally, its higher price point is highlighted as a consideration in a competitive market.

The KEF Muo (2nd Gen) is a premium Bluetooth speaker featuring an exquisitely finished aluminum body and an insightful, rhythmically positive sound with a finely shaped low-frequency response. While delivering an impressive sense of scale, the speaker suffers from a relatively blunt, strident midrange that can make vocals sound hard-edged, alongside a barebones control app and stiff market competition.
