About the KEF Mu3

An impressive wireless headphone debut from a world-famous speaker company

KEF's debut into the world of truly wireless earbuds is an elegant one. Ross Lovegrove, a sculptor and artist who helped KEF design their flagship Muon speakers, had a hand in designing them. These stylish earbuds provide detailed, accurate sound and punchy bass thanks to their expertly designed 8.2mm drivers. Couple that with their active noise cancellation and their splash-proof design, and you get a recipe for enjoyment no matter where you go.

KEF's debut into the world of truly wireless earbuds is an elegant one. Ross Lovegrove, a sculptor and artist who helped KEF design their flagship Muon speakers, had a hand in designing them.

Couple that with their active noise cancellation and their splash-proof design, and you get a recipe for enjoyment no matter where you go.

All-day listening

The Mu3s offer up to nine hours of music listening with noise cancellation. making their battery life one of the longest out there for true wireless earbuds. The charging case extends your listening time further by offering an additional 15 hours of power. The case can also quick-charge your earbuds — five minutes in the case gets you an hour of listening time.

Touch controls

Each earbud has a multi-function button that gives you access to the full suite of controls — great for when you don't have both hands free. You can play and pause your music, as well turn the volume up and down and skip tracks. If you get a phone call, you can use the button on either earbud to pick the call up and hang it up when you're done.

Advanced Bluetooth

With many true wireless in-ear headphones, one earbud pairs to your phone and then transmits signals to the other earbud. But not with the Mu3s. Here, each earbud has an indepedent Bluetooth connection to your phone. That drastically reduces the chance of latency and also means you can take calls, listen to music, and control either with just one earbud in.

Less noise, more music

A  sophisticaed active noise cancellation system blocks out external noise without compromising on sound quality. Don't want noise cancellation? Use the multi-function button on either earbud to switch to Ambient Mode, which lets you bypass that feature. Any sounds picked up by the built in microphones are played through the earbuds so you can hear happening around you.

Lightweight and snug for a comfortable fit

KEF designed these earbuds for maximum comfort. Their lightweight, well-balanced design helps them stay in place. And the four sizes of included ear tips ensure a snug fit and a perfect seal for proper noise isolation.
