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.


Precision design


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.

    I AM VERY PLEASED WITH THE SOUND QUALITY, COMFORT AND REDUCTION OF EXTERNAL SOUNDS. Review by JAA

    The headphones are comfortable to wear. They sound good. They do a good job of excluding sounds other than the sound source. (Posted on 3/4/2017)

    Everything I expected. Lightweight and good for travel. Constructed well. Blue color looks great. I rated sound quality a 5 but I'm comparing to my last headphones which were at a much lower price point and certainly do not measure up to the KEF M400. Overall I am extremely happy with the purchase and would recommend (Posted on 10/19/2015)

    M400 On-Ear Headphone Reviews from Headfonics.com | KEF Direct Review
     "... I would consider the M400 as some of the best looking and most comfortable on-ear headphones yet. They’re damn great companions for short travels or a quick music fix down on the street. All they need is your smartphone’s output and they will sound simply good. Not having any flaws is a great achievement."
