Muo – The Best Sounding Portable Bluetooth Speaker?

For over 60 years, KEF has been at the forefront of acoustic innovation, crafting high-fidelity sound experiences that resonate with listeners around the world. From our legendary HiFi speakers to cutting-edge wireless HiFi speakers, we’ve built a reputation for acoustic excellence. Now, that legacy continues with the new generation of Muo - a portable Bluetooth speaker that brings KEF’s signature sound to every corner of your life.

Whether you're relaxing at home, hosting friends, or heading outdoors, Muo delivers rich, high-fidelity audio that sets it apart from the crowd. But what makes it one of the best Bluetooth speakers on the market today?
1. Hi-Fi Technology in a Portable Form
Muo isn’t just portable—it’s powerful. Unlike many compact speakers that sacrifice sound for size, Muo draws directly from KEF’s flagship acoustic innovations:
P-Flex technology
Borrowed from our award-winning KC62 and KC92 subwoofers, P-Flex minimises distortion and enhances bass precision. The result? Clean, punchy low-end that feels far bigger than the speaker itself.
Music Integrity Engine
Adapted from our LS Wireless collection, MIE uses advanced DSP algorithms to optimise sound in real time. It ensures deep bass extension, tonal balance, and clarity across all genres—even at low volumes.
Together, these technologies make Muo a top Bluetooth speaker for those who care about sound quality.
2. What’s New in the Latest Generation?

Compared to the previous generation of Muo, the new generation represents a significant upgrade in both acoustic design and performance:
  • New bespoke racetrack low frequency driver
    With a larger cone area and longer excursion, this driver delivers deeper, more powerful bass while maintaining energy efficiency.
  • New 19mm dome tweeter
    This dedicated tweeter enhances high-frequency performance, reproducing vocals and instruments with crisp, natural detail.
  • Bluetooth 5.4 with adaptive codec support
    Muo now supports the latest Bluetooth standard, offering higher audio quality at lower bitrates, lower latency for smoother video and gaming, improved battery life, and better multi-device connectivity.
If you’re wondering which Bluetooth speaker has the best bass or what Bluetooth speaker is best for home, Muo is designed to answer those questions confidently.
3. How Does Muo Compare to Other Portable Speakers?

  • True KEF sound
    Backed by decades of acoustic excellence, Muo offers a listening experience that’s rare in its category.
  • Premium build and iconic design
    Sleek, durable, and travel-ready, Muo is designed by world-renowned visionary designer Ross Lovegrove, echoing the sculptural elegance of KEF’s legendary 2-metre-tall Muon HiFi speaker—now reimagined in a compact, portable form.
Whether you're searching for the best portable speaker for your lifestyle or the Bluetooth speaker with the best sound quality, Muo is built to impress.

Frequently asked questions

Are the KEF Coda W speakers completely wireless?

The 'wireless' in Coda W refers to how you play your music; you can stream audio wirelessly from your phone, tablet, or computer via Bluetooth. However, the speakers do require two physical connections: an interspeaker cable to link the primary and secondary speakers together, and a power cable to be plugged into a wall outlet. This design ensures they have consistent power and a perfectly stable connection to deliver the best possible high-fidelity sound.

What makes the Coda W the best speaker for vinyl players?

Coda W is the perfect partner for a turntable because it's a complete, high-performance audio system in one. The key feature for vinyl lovers is the built-in phono preamp, which allows you to connect most turntables directly to the speakers without needing an extra box. Because they are active speakers, you also don't need a separate amplifier. This creates a simple, elegant setup that delivers the warm, detailed, and authentic analogue sound you love, with modern convenience.

What is Bluetooth® 5.4 with aptX™ Lossless, and how does it improve my music?

This is the next generation of wireless audio, designed to deliver the highest possible sound quality over Bluetooth. Unlike standard Bluetooth which compresses music, aptX™ Lossless can stream music at true CD-quality, meaning you hear every single detail of the original recording without any data being lost. Combined with the stability and efficiency of Bluetooth 5.4, it means you get the freedom and convenience of a wireless connection with the stunning, high-fidelity sound you'd expect from a physical cable.

Reminder: Ensure your source device is compatible with the codec to experience true CD-quality audio.
