Master & Dynamic believes that headphones are “modern thinking caps: tools to help you focus and tune into your work while tuning out the world around you.” The Master & Dynamic MH40 Headphones ($399) look like they can carry out that montra perfectly. These headphones are built for decades of use. They feature premium leather throughout with lambskin ear pads, steel components in all high strain areas, 45mm neodymium high-performance drivers, a forged aluminum body, oxygen-free copper cables to ensure pure sound, wrapped in a woven sheath for years of use. These may be the last over-ear headphones you may ever buy.
