Sound by KEF. Design by Ross Lovegrove.
KEF’s Mu3 Noise Cancelling True Wireless Earphones are engineered to deliver pure, accurate sound everywhere. Designed in collaboration with visionary designer Ross Lovegrove, the Mu3s deliver exceptional sound on the move while being comfortable and elegant.
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.
All day, any wayRemove 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.
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.
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.
Comfort and Ease
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.
Design by Ross Lovegrove
Through working with KEF, Ross Lovegrove brings a new dimension to sound; designs that embrace beauty and technological ingenuity are an exercise in aesthetic and engineering excellence. So while the Mu3 earphones are small, they radiate a sculptural look and feel that belies their dimensions.

Solid ValueGreat sense of audiophile detail in the music, decent bass, and very good mid-range. I would have loved to have some type of control with the coupling of some type of software. In addition to these IEM being very comfortable, they fit my ears perfectly. Overall I am very pleased with the quality of the sound these IEM bring out in my music...
