Master Dynamic MH40

Master & Dynamic MH40 wired headphones with removable cable.

MH40 look stunning, they fit very well around the ear while still being a medium size headphone, have a high sensitivity, making them easy to power, so you can get great results from a portable device and they sound excellent for an under $500 headphone.

The build quality is top notch - made from steel and leather, all the parts have a solid, positive feel in the hand. The MH40 are a semi open design in a good way - they still isolate pretty well & do not leak much sound, while providing a pretty big sound field. The MH40 have a fast, deep bass response, like a closed headphone but they still provide a clean, very open midrange, like an open headphone. The treble is smoother with no sibilance, for longer listening sessions.

Cnet.com: “The MH40 is beautifully crafted from forged aluminum, stainless steel, and real lambskin leather, and its sound is competitive with that of comparably priced models. The MH40’s sound is highly detailed, yet never harsh; bass is deep, without any boom or bloat. It’s pretty incredible that a company’s debut design is so well thought out.”
