Ideal for everyday use, the KEF Mu7 Bluetooth headphones are convenient and versatile. They offer a neutral and balanced sound that perfectly enhances vocals. Their Bluetooth aptX HD compatibility, active noise-cancelling, long battery life and luxurious design are all real assets.

As the star-rating suggests, the KEF Mu7 need to be better if they’re going to appeal to as wide an audience as possible. That they’ll find their constituency is undeniable – no pair of headphones that’s as sweetly detailed, as tonally correct and sounds as out-and-out glossy as these KEFs can fail to do so. But there’s more to life than hi-fi sound, just as there’s more to life than fine dining – and who doesn’t enjoy a take-away every now and then?

There’s plenty to enjoy about the KEF Mu7. But they have a quite specific sonic stance, are prepared to let on about how hard they’re working to cancel that external noise, and are short of control options. 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.

We had high hopes for the KEFs, but sonically they’re just not up to the standards we expect from the brand
