The over-ear M500s use a full-range 40mm neodymium driver with a high-quality, super light, copper-clad aluminum voice coil that has been tuned by KEF’s engineers to deliver a powerfully musical sound with a tight, clean bass.
The M500s feature a precision-engineered aluminum frame, with breathable and sweat resistant memory foam earpads and headband.
The frame design also features a “Smart Hinge,” which is unlike most headphones that require two hinges to fold and rotate the ear pads, the M500s’ Smart Hinge can rotate on two axes, making them more adaptable to different sized (and shaped) heads. It also allows you to fold them up into a highly compact form for carrying around.
The in-ear M200 earphones utilize a user-adjustable Secure Arm that helps to keep them snug in the ear, and a rigid aluminum driver housing that eliminates unwanted vibrations and raises sound performance to new levels.
The M200s also use unique “DDD” (Dual Dynamic Driver) tech, a two-way system with a 10mm driver for the bass and a 5.5mm dynamic neodymium driver for midrange and high frequencies.
KEF’s new headphones are also compliant with the CENELEC standard (EN60065/A12)for protection against hearing damage caused by excessive sound volume.
