However you choose to get it there, once the audio information is on board your Mu7 it’s delivered to your ears by a pair of 40mm full-range dynamic drivers. A frequency response such as KEF is claiming, of 20Hz – 20kHz, is both ample and eminently achievable.Thanks to a battery that lasts for up to 40 hours, you get to enjoy the Mu7’s for longer. What’s more, its 40 hours even with Bluetooth and Smart Active Noise Cancellation engaged, meaning you don’t have to make compromises to get this generous battery life. Fast charging means that just 15 minutes of charging is enough for a further 8 hours of use.

The way any piece of audio equipment sounds is ultimately a judgement call. Someone (or some group of people) has decided on the ‘voice’ a pair of headphones (for instance) is going to have, and then fingers are crossed as to whether or not it finds favour. In the case of the KEF Mu7, it’s not difficult to picture the wish-list: five minutes inside these headphones and words like ‘judicious’, ‘precise’ and ‘mature’ all start to muscle their way to the front of the mind… Most electric vehicles are automatic – but Toyota are looking to change that for a more classic feel Which means that aside from the aluminium earcups, the rest of the KEF are unremarkable where design is concerned. Faux-leather covered memory foam forms the earpads, and there’s more of the material covering the central part of the headband. The rest of the headband, the arms and the yokes are aluminium too, and the earcups fold flat to allow the KEF-branded sem-rigid carry case to be of manageable size. If you were expecting a long list of features similar to rival pairs of headphones such as the Sony WH-1000XM5, Bose Noise Cancelling Headphones 700 and the Sennheiser Momentum 4 Wireless, the KEF Mu7 are a bit of a mixed bag.

They all have a history of consistently producing excellent speakers, but largely useless and/or over-priced designer headphones. No doubt they’ll find their market with the cloth-eared style over substance brigade that today’s What Hi-Fi pitch towards. Surely only a matter of time before Linn or Naim join in.

Renowned for his sculptural, flowing forms, Ross Lovegrove is a visionary designer. The Mu7’s have a purity of design that reflects their sound quality. The smooth, seamless design is available in a choice of Silver Grey or Charcoal Grey finishes. And in our opinion, the result is a distinctive-looking pair of over-ears. The headphones have a liquid metal vibe and feel about them. The teardrop shape of the earcups looks refined and sophisticated, while the smooth surfaces are nice to the touch. Battery life is a perfectly respectable 40 hours from a single charge of the 1100mAh lithium-ion battery, and that’s with ANC switched on and a wireless connection made. Just a 15 minute charge via USB-C is sufficient to keep the Mu7 playing for another eight hours. And unlike quite a few rivals we could mention, KEF’s figures are all completely realistic.

In love with my Mu7! They're so comfortable, can wear them for hours. Sound quality is amazing, you can hear every detail - and the ANC is so good which is perfect for my commute on the tube which can get quite noisy. Good on calls as well for both work through Teams/Zoom but also to use for a normal phone call I haven't had any issues. The touch function is quite sensitive so has taken some getting used to but now I know how it works it's really simple and easy.However, a couple of the features we’ve come to expect from premium wireless headphones like the KEFs are missing. KEF sound, Ross Lovegrove design.” That’s how the British brand announced the launch of its new KEF Mu7 noise-cancelling Bluetooth headphones. A design by Ross Lovegrove
