About The KEF Mu3 In-Ear Noise Cancelling Headphones
With KEF's Mu3 Noise Cancelling True Wireless Earphones you are free to enjoy pristine sound everywhere. KEF has once again collaborated with visionary designer Ross Lovegrove, the latest step in a relationship that started with the incredible Muon loudspeakers, through Muo Bluetooth speakers and now the Mu3 earphones. Designed to be both comfortable and elegant, Mu3's flowing, sculptural lines and smart engineering ensure a perfect fit while also delivering exceptional sound on the move.
KEF's Signature Pure and Accurate Sound: Each of the Mu3 earphones' sculptural enclosures contains an 8.2mm full-range dynamic driver. These are expertly tuned by the same KEF engineering team responsible for their loudspeakers, ensuring consistently pure and accurate sound on the move, with rich midrange, detailed bass and crisp high tones, capable of revealing even the most subtle nuances of music.
Active Noise Cancellation: The audio performance of the Mu3 earphones benefits from KEF's specially tuned Active Noise Cancellation, which eliminates external noise without affecting the details that bring music to life. The earphones also boast Ambient Mode, where at the touch of a button Active Noise Cancellation is disengaged and instead the audio picked up on the microphones is played through the earphones, bypassing passive noise reduction and providing you with instant clarity on what is going on around you.
Hassle-Free with Bluetooth 5.0: Mu3's audio performance is further enhanced by the introduction of simultaneous transmission, where both earphones receive a signal at the same time, rather than the more usual approach where audio is sent to one earpiece and relayed to the other, therefore running the risk of introducing latency. Coupled with Bluetooth 5.0 connectivity, simultaneous transmission means the Mu3 earphones deliver a seamless performance, are simple to connect and exceptionally stable on both iOS and Android devices.
All-Day Listening and Fast Charging: A high-capacity battery combines with smart power management and fast-charge technology to ensure the Mu3 earphones keep going as long as you do. Mu3 can keep 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. And don't worry if you get caught out in a shower, because with their IPX5 splash-proof design, these headphones are good for a little dancing in the rain.
Compact, Ergonomic Design: The Mu3 earphones are perfectly balanced in the ear thanks to the smart way they are weighted, which stops them wanting to fall out. A comprehensive analysis of different ear shapes and sizes has led to the development of four subtly different sized ear tips that are designed to rest on the ear concha to ensure you get the most comfortable fit for your ears, 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 earphones feature a highly intuitive, incredible responsive user interface. And because they know you may be doing other things while you listen to music, each of the earbuds includes a multi-function button for full control of music playback, volume and calls for instant control when only one hand is free.
Design by Ross Lovegrove: Renowned for his innovative approach and flowing, sculptural forms, Ross Lovegrove brings a new dimension to sound. Through design that embraces both beauty and technological ingenuity, Lovegrove's ongoing collaboration with KEF is an exercise in aesthetic and engineering excellence.
The Mu3 earphones may be small, but they radiate a sculptural look and feel that belies their compact dimensions. The collaboration with Ross Lovegrove has once again resulted in a product that is the very definition of technology as art, and a design that smartly complements the KEF philosophy.
