The MH40 Master & Dynamic headphones marry vintage aesthetic with modern construction and materials. Contrasting machined aluminum against natural leather presents a visually engaging set of headphones. Clean edges contrasted against round hand-stitched further this effect. The independently swiveling and adjustable ear cups end up making the headphones fair ergonomic and portable, a convenience not afforded by most high-grade headphones. Ultimately, however, they are still headphones and headphones with poor sound quality are poor headphones. In this regard, the MH40 do not fail and produce a clear, balanced sound staying true to its high fidelity aesthetic.
