Pursuing the success of the highly acclaimed M-series, KEF's M400 portable headphones combine advanced technologies with precision engineering, robust lightweight construction and exceptional wearing comfort and compatibility with virtually any smartphone or portable device.
With the combination of precision tuned high performance drivers and aluminium voice coils the M400 creates neutral and clear sound faithful to the original recording with sharp, intricately detailed treble, smooth midrange and tight, clean bass response.
KEF M400 has all the makings of a true design classic with lightweight, compact design that is and built to withstand years of use on the move as well as at home. The invisibly hinged folding frame is engineered from precision-machined cast aluminium, with supremely comfortable supra-aural earpads and a leather headband.
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.
High resolution sound made portable.
High Resolution Sound
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.
Lightweight, compact and built to withstand years of use. The invisibly hinged folding frame is engineered from precision-machined cast aluminium, with supremely comfortable supra-aural earpads and a leather-covered headband.
Superior Comfort & 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. The light, sturdy aluminium frame exerts the right amount of gentle pressure.
Complementing all Apple and most other digital devices, M400 features an integrated in-line microphone and remote on a detachable cable, allowing you to operate the play functions or switch between calls and music.
