After the re-release of the KEF LSX II, the brand’s new wireless hi-fi system, the company has unveiled its latest wireless noise-cancelling headphones: the KEF Mu7. This is not KEF’s first foray into the portable headphones market. In 2016, the British brand launched its first noise-cancelling model, the KEF Space One, followed by the Bluetooth wireless version KEF Space One Wireless. These followed the brand’s first headphones, the KEF M500, released in 2013. The Mu7 model features Bluetooth aptX HD, Smart Active Noise Cancellation, Clear Voice Capture and a long battery life… All concentrated in a unique design by Ross Lovegrove.
A design by Ross Lovegrove
As we saw in 2017, KEF doesn’t hesitate to collaborate with big names like Porsche Design (also read: KEF Porsche Design: a Bluetooth speaker and two pairs of headphones) and ECCO Design designer Eric Chan for the KEF Blade speakers.
A UFO for some, a work of art for others, the KEF Mu7 headphones have an original design that sets them apart from the competition. To do this, the brand continues its partnership with designer Ross Lovegrove that began in 2005. As the creator of the popular Muon speakers, KEF Muo portable Bluetooth models and KEF Mu3 True Wireless IEMs, Ross Lovegrove takes the rounded lines that made these pieces of equipment so successful. Renowned for his avant-garde approach, he has worked on the design of Sony’s Walkman and the iMac computer.
The new KEF Mu7 headphones return to the visionary design and sculptural forms created by Ross Lovegrove. We find a circumaural design as well as an ergonomic aluminum structure. The headphones are designed to look good, but also to offer effective isolation and a comfortable fit. It has a featherweight of 309g, thick memory foam and a particularly thin headband. The large earpieces feature touch controls for playback, as well as volume control.
Available in two stylish colors, Silver Grey and Charcoal Grey, the headphones feature leatherette-covered earpads. The latter swivel 90° to allow for flat folding. This model comes with a hard case for easy and convenient transportation.
Authentic KEF sound and intelligent active noise cancelling
These headphones combine the creative approach of the famous designer with KEF’s commitment to optimal sound. For this purpose, this new model is equipped with 40mm transducers developed by KEF. The brand refers to “perfect audio performance, revealing the most subtle acoustic details”. Their Qualcomm 5.1 Bluetooth chip supports SBC, AAC, aptX and aptX HD codecs to enjoy good audio quality up to 24-bit/48kHz wirelessly.
The headphones also have an active noise cancelling system to enjoy your music without hearing background noise. The technology, called Smart Active Noise Cancellation, works with multiple microphones. The latter are associated with a specific algorithm that targets certain frequencies for better noise suppression processing. Qualcomm cVc technology completes the picture to ensure optimal call quality by capturing only voices.
The KEF Mu7 also have a rechargeable battery that provides up to 40 hours of battery life. A fast charge via their USB-C port provides 8 hours of playback after just 15 minutes. The icing on the cake is a 3.5mm mini-jack input for playback via analog sources and allows the headphones to be used in passive mode when the battery is flat.
