Drawing on KEF’s unrivalled heritage of design innovation in pursuit of the clearest and most accurate sound reproduction, they bring the pleasures of high resolution acoustics to the users of virtually any portable device at an extremely competitive price.
High resolution sound on the move
Seriously cool on-ears with sophisticated drivers in a stylishly compact design that combines lightness and outstanding build quality with KEF’s characteristically accurate, natural sound. Like its highly acclaimed M500 sibling, the M400’s astonishing sound quality derives from KEF’s ultra-light full range 40mm dynamic neodymium driver, which boasts a CCAW (copper clad aluminium wire) voice coil painstakingly tuned to deliver the natural, seductively musical response for which KEF speakers have always been famous: crisp, intricately detailed highs, seamlessly fluid midrange and tight, clean bass.
Looking as good as they sound: engineered from cast aluminium with a silky premium finish, folding up neatly for storage and available in four stylishly distinctive finishes. Instantly recognisable by its smooth contemporary lines and striking satin colour finishes, the compact M400 is built to last, with a precision-machined cast aluminium frame that has a satisfying premium heft without being heavy to wear, and is hinged to fold neatly away for ease of storage when not in use. There are four stylish finishes to choose from: Racing Blue, Sunset Orange, Deep Black and Champagne White.
Excellent comfort and noise isolation
Class-leading ergonomics, with memory foam and breathable pads that conform to the ear to exclude ambient noise and ensure comfortable prolonged listening. With high density memory foam covered in soft, sweat resistant and hardwearing protein leather, the ‘race-track’ ear pads assume the shape of the ear to form an effective acoustic seal that prevents leakage, while the robust aluminium frame is engineered to maintain a gentle pressure that ensures a comfortable, secure fit in any conditions, even for long periods.
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. As the detachable cable has standard 3.5mm connectors at both ends, users can easily customise the connectivity to their requirements. Like other KEF headphones, user safety is assured in line with the CENELEC standard for protection against excessive sound pressure.
