KEF Mu3 Noise Cancelling True Wireless Earphones are designed, in collaboration with visionary designer Ross Lovegrove, to deliver top quality sound whilst on the go as well as being comfortable and stylish.

Sculptural Design
KEF has combined with visionary designer Ross Lovegrove, known for his sculptural designs, to create a set of earphones that are innovative and stylish, yet still comfortable. The MU3 earphones follow similar aesthetics to the previous collaboration’s Muon speakers and Muo headphones.

Mu3 Drivers
Each earphone contains an 8.2mm full-range driver that is tuned to ensure a pure and accurate sound with a rich midrange, detailed bass and crisp, clear highs, which are capable of revealing the subtle nuances in the music.

Noise Cancellation
KEF’s Mu3 earphones have Active Noise Cancellation to remove external noise without affecting the audio performance. It also features ‘Ambient Mode’, which disengages the Active Noise Cancellation to allow you to hear what is going on around you.

All-day listening
The Mu3’s can play for up to 24 hours, with 9 hours of on-board battery life, plus up to 15 hours with the charging case. Fast charging option also provides up to an hours worth of use from only 5 minutes charging.

Bluetooth Connectivity
The Mu3’s have Bluetooth 5.0 connectivity for a strong performance that is easy to connect and highly reliable with iOS and Android devices. They also receive signal at the same time, rather than one relaying to the other, this is better for connectivity.

Comfortable and Lightweight
Four different sized ear tips are supplied, which are developed so you get the most comfortable fit, while also providing the seal for noise isolation and to keep them securely in place.
