KEF might have made its name churning out top-notch loudspeakers for the past 60 years, but what are in-ear headphones if not just tiny speakers that go in your ears? Joining other hi-fi heavyweights such as Cambridge Audio, Bang & Olufsen and Klipsch, KEF’s first true wireless buds are not messing about. Priced at £199, the Mu3 have 8.2mm full-range dynamic drivers, active noise-cancelling, Bluetooth 5.0 and IPX5 water resistance, all squeezed into a svelte chassis that KEF claims is specially weighted to stop them making a break for it when you have to run for the bus. The charging case adds 15 hours of battery life to the nine stored in the buds, but just five minutes on charge will fill them with enough juice to last an hour. You get four different sets of ultra-soft silicone tips in the box to make sure you can find a pair that fit your earholes perfectly, because no matter how hard you try, that’s never going to happen with your favourite pair of speakers.
