KEF’s New Mu7 Wireless Headphones Provide Sleek Design, Crisp Audio, And 40 Hours Of Battery Life

Today KEF announced the release of the $399 KEF Mu7, their latest pair of wireless noise-canceling headphones.

The KEF Mu7 wireless headphones are designed by British designer Ross Lovegrove, who also worked with the brand on the flagship Muon loudspeakers, Muo portable speakers, and Mu3 earphones. They feature a sleek, minimalist aluminum design that folds flat for easy storage and touch controls on the right earcup to access many functions with simple swipes and taps.

From an audio standpoint, they offer high-quality sound via 40mm full-range dynamic drivers mounted inside. They also have Bluetooth 5.1 and the Qualcomm aptX™ HD codec for stable, high-bitrate audio. Additionally, they have Clear Voice Capture (cVc) technology for phone call clarity.

In addition, they have sophisticated active noise cancellation technology to filter out unwanted sound. The tech uses multiple filters to capture external noises before applying a special algorithm to target specific frequencies.

Marlboro, NJ – October 13, 2022: Featuring inimitable sound by KEF and design by long-term collaborator Ross Lovegrove, the KEF Mu7 Wireless Headphones deliver an uncompromising audio experience paired with understated style.

An exercise in both engineering and aesthetic excellence, KEF has continued its partnership with visionary designer Ross Lovegrove to produce the Mu7. Renowned for his innovative approach and flowing, sculptural forms, Lovegrove has created an over-ear headphone design which is refined, sleek, and a harmonious addition to the wider Ross Lovegrove Collection for KEF. Lovegrove has previously worked alongside the brand to shape the definitive Muon loudspeakers, Muo portable speakers, and Mu3 earphones.

KEF draws upon years of commitment to technological innovation and high-performance audio equipment to continue its mission to present music as it was made to be heard. Focusing on the nuances that imbue sound with heightened levels of significance, KEF preserves the integrity of a recording with little intervention, presenting a revealing listening experience that offers a pure and accurate representation of the original recording.

Available in two sleek colourways, Silver Grey and Charcoal Grey, the Mu7 headphones present precision-engineered, ergonomic aluminium construction. A lightweight, durable headband delivers a snug acoustic seal, with minimal ear pressure. The memory foam ear pads mould to the shape of the head, improving both passive and active noise cancellation and bass response. A swivel point above the ear cups allows the headphones to be rotated and flattened, ideal for compact transport.

A capacitive touchpad on the right ear cup allows users to answer calls, skip tracks and adjust volume through a series of intuitive taps and swipes. Lovegrove notes that “If you are wearing a particular type of headphones, they are an extension of you. Well, what is the best interface? Your finger. It’s like putting your hand over your ears, there’s this gestural elegance.”

Custom tuned by the KEF engineering experts, the Mu7 headphones integrate enhanced codec technology to deliver KEF’s instantly recognisable

high-resolution sound quality, wirelessly. In each of the closed-back earcups sits a full-range dynamic driver for a pristine audio performance that reveals even the most subtle acoustic details.

Sophisticated Smart Active Noise Cancellation technology uses multiple filters to capture environmental sound, before applying a specialised algorithm to target individual frequencies. For hands-free phone calls, Clear Voice Capture (cVc) isolates the voice of the speaker and minimises all other noise picked up by the microphone, ensuring crystal clear calls regardless of the environment.
