These stylish on-ear M400 headphones from KEF pack outstanding sound quality from state-of-the-art driver technology in a sleek design that has been engineered for total comfort.
High Res Music on the Move
As you might expect from people who are obsessed with high resolution sound, the beauty of the M400 is more than skin deep. With KEF’s ultra-light 40mm neodymium driver and copper clad aluminium wire (CCAW) voice coil, the M400 reveals all the glories of the original performance: crisp, intricately detailed highs, seamlessly fluid midrange and tight, clean bass. Music you can feel – and so realistic, you can almost touch it. Your favourite tracks never sounded so good.
Lightweight, compact and built to withstand years of use on the move as well as at home, the M400 has all the makings of a true design classic. The invisibly hinged folding frame is engineered from precision-machined cast aluminium, with supremely comfortable supra-aural earpads and a leather-covered headband contrasting with four silky premium finishes: Racing Blue, Sunset Orange, Deep Black or Champagne White.
Excellent Comfort & Noise Isolation
Padded with high density memory foam covered in soft, sweat resistant protein leather, the ball-jointed ‘race-track’ ear pads fit the exact shape of your ear and form an effective seal that cuts out external noise while preventing sound leakage. The light, sturdy aluminium frame exerts the right amount of gentle pressure that allows you to enjoy your music in comfort for as long as you want.
Fits All Your Devices
Complementing all Apple and most other digital devices, M400 features an integrated inline microphone and remote control on a detachable cable, allowing you to operate the play functions or switch between calls and music. The frame is discreetly hinged to fold neatly away for ease of storage when not in use, and like other KEF headphones, the M400 protects you against excessive sound pressure in line with the CENELEC standard. Sublime sound quality, thanks to KEF innovation. Engineered for durability and class-leading comfort. And a flair for design that makes other headphones look boring. At the price, nothing else comes close.
