Here is a KEF M400 over the ear headphones
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.
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.
