About the Mu3

The KEF Mu3 are premium true wireless earphones engineered to deliver KEF's signature pure and accurate sound with rich midrange, detailed bass, and crisp high tones. Designed in collaboration with visionary designer Ross Lovegrove, they feature specially tuned active noise cancellation that eliminates external noise while preserving musical detail. The earphones employ simultaneous transmission technology where both earpieces receive the signal at the same time for seamless, stable performance. With ergonomic sculptural design, IPX5 splash-proof rating, and up to 9 hours of battery life with ANC enabled, the Mu3 offers all-day listening comfort. The charging case provides an additional 15 hours of battery, and quick charging delivers 1 hour of use after just 5 minutes. Includes four sizes of silicone ear tips for a secure, customized fit and comes with a 2-year warranty.
