Overview

Our take on the KEF MUO

Best part of my job? Taking the gear I write about home and trying it out — like I did with the KEF MUO Wireless Speaker. When I lifted it out of the box, it had the heft of a quality-built speaker, and its smooth aluminum shell was cool to the touch. And when I paired it with my smartphone, I discovered it had the sound of a quality-built speaker, too. KEF's been designing innovative high-performance speakers since 1961, and this is a worthy addition to their line. The sound was spacious and warm, yet richly detailed.

KEF MUO

"Party mode" lets you play the same signals through two MUOs simultaneously, or you can use them as a left/right stereo pair.

Beautifully crafted sound

Best part of my job? Taking the gear I write about home and trying it out — like I did with the KEF MUO Wireless Speaker. When I lifted it out of the box, it had the heft of a quality-built speaker, and its smooth aluminum shell was cool to the touch. And when I paired it with my smartphone, I discovered it had the sound of a quality-built speaker, too. KEF's been designing innovative high-performance speakers since 1961, and this is a worthy addition to their line. The sound was spacious and warm, yet richly detailed.

Amazing sound quality

The MUO's two Uni-Q® point source driver arrays are more than just full range speakers. The central tweeter dome is decoupled from the outer cone, allowing it and the woofer to move independently. The result is greater definition and accuracy in the highs, as well as the midrange. A long throw passive radiator reinforces the low tones, giving the sound a full-bodied texture. The driver arrays are positioned for maximum sound dispersion and to minimize interference with each other. When I cranked up the volume, the sound did indeed fill the room without sounding harsh or distorted.

Built-in Bluetooth with aptX®

You can stream music wirelessly from your smartphone or tablet to the MUO via Bluetooth. The system includes aptX audio coding, an advanced type of Bluetooth wireless streaming that retains virtually all the detail of the audio signal it carries. The MUO's sophisticated digital-to-analog converter renders your music with accurate detail.

The KEF MUO app

While the MUO's great right out of the box, the free KEF MUO app lets you do even more with this remarkable portable speaker. The app gives you step-by-step instructions for setup. It also lets youpairtwo MUOs together, as I did (I do love my job). You can configure them as a left/right pair for true stereo separation — a great option for a desktop sound system. Or you can have both MUOs play simultaneously — ideal for a deck party where you need music evenly dispersed.

Great sound, not crazy loud but very good. Clear and good volume. I wish it could play louder, I'm a bit of a lover of loud music, but for the size of the thing, it rocks. Built very solid. After 8 months I ordered a 2nd so I can have stereo. Wish it had USB-3 power connection.

Crutchfield Customer Review (What's this?)

I had read numerous reviews on Amazon and other sites. I went with Crutchfield because of the great support 2 day free shipping and 60 day guarantee return. Only thing this is staying here. Far exceeded my expectations. I also have the B&W MM-1's from Crutchfield as well. Wanted a Bluetooth option and something I could travel with as well

Pros: Detailed Sound Plenty of Bass Vocals are outstanding Soundstage very open,natural open and non-fatiguing Seriously took less than 15 Seconds to pair with several Apple products including my MacBook and IPod 5th Gen. Far exceeded my expecations

Cons: None. This little speaker has big sound and can fill a room up at reasonable levels

Features

Pure KEF Sound: Designed by Ross Lovegrove and engineered by KEF, MUO is packed with innovative technologies to deliver uncompromised KEF quality sound when you're streaming music wirelessly from your mobile device or computer. You'll be astonished by the sweet, natural treble, fluid midrange and clean, tightly controlled bass.

Uni-Q "Point Source" Driver Array: Thanks to a clever new compact version of KEF's legendary Uni-Q "Point Source" driver array and a powerful new bass radiator, the MUO fills the room with stunningly accurate sound.

  • Wide Sound Dispersion: The Uni-Q driver array delivers an astonishingly wide soundstage that fills a room with full-bodied, stunningly clear sound, and reproduces the higher registers with pinpoint accuracy.
  • Non-Directional: The MUO's drivers which flank the central passive bass radiator, are configured to only give treble output from the right hand unit as you face the MUO placed horizontally. This reduces interference to achieve a more non-directional and room-filling sound.

Rigid Enclosure: These KEF MUO's drivers are mounted within an immensely rigid inner molding that is encased in an acoustically inert aluminum shell.

15W Amplifier: The MUO's Uni-Q "Point Source" driver array is powered by an integrated 15W amplifier for great sound and low distortion at any volume level.

Sophisticated DAC: The MUO utilizes a sophisticated digital-to-analog converter and other high-quality internal components for continuous and consistent sound quality.

Bluetooth 4.0 w/ aptX: With its built-in Bluetooth (version 4.0), you are able to wirelessly stream stored music and music apps from your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, Windows Phone/PC, Mac computer/laptop and other Bluetooth source devices to the KEF MUO speaker. You'll still need to control music playback and view song/artist info from your Bluetooth source device. Up to 8 devices can be paired to the MUO with two devices connected at the same for easier switching (however, only one can be used for music playback at a time).

  • aptX: In addition to support the standard Bluetooth SBC codec, the KEF MUO offers support for aptX. With aptX, you can stream CD-quality sound from aptX compatible devices (like Android OS 4.0+). Now your wireless music sounds rich, full, and natural with less compression.
  • NFC: With most Android mobile devices, you can benefit from the NFC (Near Field Communication) "tap-to-pair" function - just hold the device against MUO and they're paired ready to stream your music in seconds. Other Bluetooth source devices can be paired via SSP (Simple Secure Pairing) with a single press of a button and no PIN code to enter.
Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the KEF MUO.

KEF MUO App: Download the KEF MUO App onto your Apple iOS 7.0+ or Android OS 4.0+ device for quicker Bluetooth connection, music library management, speaker status monitoring and multi-speaker pairing.

Stereo Pairing & Dual Connect Mode: Synchronize a pair of MUO speakers for superb CD-like quality stereo reproduction or select "Dual-Connect" party mode for large gatherings, so that everybody experiences the same superlative full-range response.

Aux Input: In addition to Bluetooth wireless music streaming, the MUO features a 3.5mm Aux input for connecting an external portable audio device that features an analog output or headphone jack.

Vertical or Horizontal Placement: The MUO automatically optimizes its output to suit vertical or horizontal positioning, so you always enjoy the same remarkable acoustic depth and definition.

Rechargeable Battery: The KEF MUO has a rechargeable battery with up to 12 hours of playback time, and switches itself off automatically when not in use to prolong battery life. The MUO's battery can be charged using the included AC power adapter. It takes approximately 3 hours to fully charge the MUO's battery.
