These premium on-ear headphones are crafted from aerospace-grade aluminium, steel, memory foam and supple materials, to provide ultimate strength, comfort and durability. The customised 40mm dynamic drivers have been enhanced to deliver a powerful, yet highly defined audio experience. Each aluminium speaker chamber has been hand prepared then anodised in a deep matte finish. Designed for everyday use, the universal one button remote and in-line mic gives you control over your music and incoming calls. Each headphone has been hand-built and individually sound tested by our engineers in Britain.
