On the edge of the earcup you also have access to buttons for noise-cancelling, power and Bluetooth pairing. This is really very important for me because ONLY real leather earpads are good for me (leatherette or artificial leather ALWAYS making my ears hot and/or sweating very quickly). The latter are associated with a specific algorithm that targets certain frequencies for better noise suppression processing.

KEF's ANC party piece is Smart Active Noise Cancellation – the headphones use an algorithm to target certain frequencies to cancel out based on your environment. Given some appropriate content of appropriately sizable resolution to deal with, there’s plenty to like - admire, even - about the sound the Mu7 make.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 swivel point above the earcups allows the headphones to be rotated and flattened, ideal for compact transport. Like all noise-canceling headphones, the KEF Mu7 is a closed-back design and each earcup has a full-range dynamic driver. 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. They're made of aluminium, which should make them feel more premium than the Sony XM5 and Sennheiser Momentum 4 Wireless, both of which feel less luxurious than their predecessors.

The active noise-cancellation (ANC) uses filters to capture background sounds before using a specialised algorithm to target individual frequencies.However, a couple of the features we’ve come to expect from premium wireless headphones like the KEFs are missing. Today, we have millions of users a month from around the world, and assess more than 1,000 products a year. In an area of the market as fearsomely competitive as this is, what might usually be considered fairly minor shortcomings are enough to comprehensively scupper a product’s chances. The clamping weight is a little more forceful than a rival like the Sony XM5, but they do feel secure, and our ears didn’t warm up too quickly during longer listening sessions. The soundstage they create is big, convincingly laid out and absolutely rock-solid in its focus and separation.

Given the competition the Mu7 are up against, it was always going to take a special performance for them to make their mark, but it’s disappointing that the KEFs sound so far behind some rivals. Once Mu7 is connected to device 2, you may reconnect the Mu7 to your device 1 on its Bluetooth setting page. Muon speakers, Muo Bluetooth speakers, Mu3 earphones… Today KEF unveils a new hi-fi device designed by the great designer Ross Lovegrove: the Mu7 wireless headphones.Editorial independence means being able to give an unbiased verdict about a product or company, with the avoidance of conflicts of interest. Using a capacitive touchpad on the right-hand earcup, you can control a whole host of features via simple tap and swipe motions. Sophisticated Smart Active Noise Cancellation technology uses multiple filters to capture environmental sound, before applying a specialised algorithm to target individual frequencies.
