The black M400 from KEF are high-fidelity on-ear headphones, offering high-resolution sound to the discerning audio enthusiast. The headphones feature a full-range 40mm dynamic neodymium driver, which boasts a copper-clad aluminum wire (CCAW) voice coil that is tuned to deliver a natural musical response with crisp detailed highs, fluid mid-range, and tight, clean bass.
The lightweight and foldable casing is precision-machined from cast aluminum with a silky premium finish, while the soft leather and high-density memory-foam earpads assume the shape of the ears and offer a tight acoustic seal with all-day comfort. The detachable 4.3' / 1.3 m cable features an inline mic and volume control that is compatible with Apple products, as well as most other mobile devices. The M400 ships with an in-flight adapter and a carrying pouch.
