Sound by KEF. Design by Ross Lovegrove.

The Sound & Design Journey Continues

Mu3 is the new chapter in the sound and design journey of KEF and Ross Lovegrove. Renowned for his innovative approach and flowing, sculptural forms, Lovegrove and KEF have already created the Muon and Muo. Mu3 defines technology as art; a design that complements KEF’s obsession with pure, accurate sound.

Pure, Accurate Sound…Anywhere

Each of Mu3’s sculptural earphones contains a full-range driver expertly tuned by the same engineers behind KEF loudspeakers. This ensures pure and accurate sound on the move, with rich midrange, detailed bass and crisp high tones, capable of revealing the subtle nuances of your favourite music.

Remove Or Reveal Your Surroundings

KEF’s specially tuned Active Noise Cancellation eliminates external noise without affecting the details that bring music to life. At the touch of a button, Mu3’s Ambient Mode disengages noise cancellation providing you with instant clarity on what is going on around you.

All-Day Listening

Mu3 earphones keep going as long as you do, keeping you entertained for up to 24 hours, with 9 hours on-board battery life, plus up to 15 hours with the charging case. And, if you are desperate to use them quickly, fast charging delivers a full hour of use from only 5 minutes charging.

Seamless Connectivity

Both Mu3’s earpieces receive a signal at the same time, rather than the usual approach where audio is sent to one and relayed to the other. Coupled with Bluetooth 5.0 connectivity, this means they deliver a seamless performance, are simple to connect and highly stable with iOS and Android devices.

Designed For Your Ears

The Mu3s are perfectly balanced in the ear thanks to the smart way they are weighted. Four subtly different sized ear tips are designed to rest on the ear concha, ensuring you get the most comfortable fit, while also providing the perfect seal for noise isolation and to keep them securely in place.

Intuitive Control

KEF’s engineers understand that control is vital when using earphones, which is why the Mu3 features a highly intuitive, incredibly responsive user interface. Each of the earbuds includes a multi-function button for full control of music playback, volume and calls for instant control.
