KEF Mu7 Wireless Active Noise Cancelling Headphones, Charcoal Grey

Product Information

Denon D2000, B&W P7 (sold), Audeze EL-8O(sold), Fostex TH-X00 Mahogany, Beyerdynamic Dt880 600ohms, M-Audio Q40 (MIA), AKG K240 MKII, Ultrasone HFI 780, B&W PX7 S2, Beats Studio 3 (they were a gift) --> Audioquest DragonFly 1.2, Schiit Asgard So far, it’s a feature-set that’s entirely appropriate for a product of this type and cost – but there are a couple of blanks on the KEF’s spec-sheet. Unlike almost every price-comparable rival (and quite a few that are fair bit more affordable, too), there’s no control app accompanying the Mu7. This means no adjustable EQs, no sliding scale of ANC, no firmware upgrades or any of the other stuff I’ve come to expect where wireless headphones of all types are concerned.

With such a long battery life, it’s good to see that KEF has ensured that there’s comfort to match. Memory foam ear cushions fit to perfection while the padded headband clamps to your head with just the right amount of force – not too tight but tight enough to ensure a good seal with the earpads.

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. 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. There’s no transparent mode which allows you to have a conversation while wearing them and there’s no automatic pausing when you either lift an earcup or remove them from your head. They don’t sound like major problems, but when you’re used to experiencing them on rival products it’s surprising how much they can elevate the user experience when executed correctly.

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.

Ergonomic design featuring precision-engineered aluminium frame and breathable leatherette memory foam ear cushions It’s a tough assignment, and, to be honest, you’d forgive the company for concentrating more on its excellent, modern, all-in-one hi-fi solutions such as the five-star LSX II and LS60 Wireless and giving premium wireless headphones like the KEF Mu7 a swerve.
