KEF's Finest Wireless Headphones
The KEF Mu7 sits at the top of KEF's personal audio range, bringing the same acoustic philosophy that has defined the brand's award-winning loudspeakers to a pair of over-ear wireless headphones. Designed for the serious music listener who refuses to compromise on sound quality, the Mu7 combines premium materials, class-leading active noise cancellation, and high-resolution Bluetooth audio in a refined, portable package.
40mm Driver with KEF Acoustic Heritage
At the heart of the Mu7 is a custom 40mm dynamic driver, developed drawing on KEF's decades of speaker engineering expertise. The driver is tuned to deliver a wide, natural frequency response with the kind of clarity and imaging that KEF's dedicated hi-fi listeners expect. Each driver is precisely matched to ensure a consistent stereo experience, with a controlled low end, detailed midrange, and smooth, extended treble.
Wireless Connectivity and High-Resolution Audio
Bluetooth 5.1 provides a rock-solid wireless connection to both iOS and Android devices, while support for the Qualcomm aptX HD codec enables high-resolution audio playback at up to 24-bit/48kHz. Standard SBC and AAC are also supported, ensuring broad compatibility. A Bluetooth range of up to 10 metres gives you freedom of movement without dropouts.
Active Noise Cancellation and Battery Life
The Mu7's hybrid active noise cancellation system effectively blocks ambient noise, making it equally at home on a commute or in a busy office. With ANC and Bluetooth both active, the 1100mAh lithium-ion battery delivers up to 40 hours of continuous playback. If you need a quick boost, fast charging gives you 8 hours of use from just 15 minutes at the socket.
Comfort and Build Quality
The Mu7 is built to be worn for extended listening sessions. Premium memory foam ear cushions and an adjustable headband distribute weight evenly, while the over-ear design provides passive isolation in addition to the active noise cancellation. Folding flat for travel, the headphones are supplied with a carry case, 3.5mm audio cable for wired use, and a USB-C charging cable. Available in Charcoal Grey and Silver Grey.
