KEF Mu7 Wireless Active Noise Cancelling Headphones, Charcoal Grey

Product Information

Of course, there’s a bit more to these KEF than a high-sheen, smooth and rather self-consciously mature presentation. Five minutes in the company of a TIDAL-derived stream of Cornflake Girl by Tori Amos allows the Mu7 to explain a lot of what they’re all about – and a lot is a lot of what they’ve got. The KEF Mu7 are solidly built, though. The aluminium casework feels robust and premium, which is just what you want from headphones at this price point. The arms that attach the headband to the earcups don’t feel flimsy and they also allow for a good amount of movement, so you can get the 40mm full-range drivers angled properly and fit over the whole of your ear without any gaps where sound can leak out and noise can leak in.

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.

For the most part, the Mu7 are premium wireless over-ear headphone business as usual. The slender arms and yokes are of smooth, expertly fitted aluminium, while the earpads and the central portion of the headband are breathable leatherette – the earpads are filled with memory foam.

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. Each earcup has a couple of cutaways near the top that act as mic openings. The right earcup also has a smaller mic opening towards the bottom, and there’s also a little LED down here too - it lets you know what’s what regarding charging, pairing, power status and so on. turbohobbit said:I agree. I've have the KEFs for about 6 weeks now and they're grand. Sure they aren't the bassiest headphones out there but they are top notch for proper unadulterated sound replication - exactly what you'd expect from a speaker maker. To be fair, I do run them through an iFI Go Blu DAC for a little extra volume and filtering but that's my choice - you certainly don't have to. For the design of the Mu7, KEF has enlisted the services of long-time collaborator Ross Lovegrove. Anyone familiar with this work for the company, from the huge Muon loudspeakers to the grabbable Muo wireless speaker, will know what to expect here (beyond a model name that starts ‘Mu’) - the Mu7 are an organically flowing combination of bumps and recesses. Or, at least, they are as far as the earcups are concerned - that’s about the only area of a pair of over-ear headphones that doesn’t have its form utterly dictated by its function.

It’s difficult to know for sure, of course, but if the words good taste and grown-up weren’t as high on the list of Mu7 sonic requirements as detailed and high-fidelity then I’ll eat my metaphorical hat. 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. However, a couple of the features we’ve come to expect from premium wireless headphones like the KEFs are missing.
