Designed in collaboration with visionary designer Ross Lovegrove, the KEF Mu3 Active Noise Cancellation True Wireless Earphones deliver exceptional sound on the move while being comfortable and elegant. Each of Mu3’s sculptural earphones contains a full-range driver expertly tuned by the same engineers behind KEF loudspeakers. This ensures a rich midrange, detailed bass and crisp high tones, capable of revealing the subtle nuances of your favourite music.

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.

Designed for your ears, these earphones 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 and each of the earbuds includes a multi-function button for full control of music playback, volume and calls for instant control.
