Master & Dynamic makes some of the most amazing high-end headphones money can buy at under $400. We were very impressed with the amount of quality and attention to detail when we tested the company's flagship MH40 over-ear headphones, which are fairly large but immensely comfortable to wear. And for those looking for something a little more portable to use while out and about, we have finally gotten our hands on Master & Dynamic's MH30.

These are the company's smaller and lighter on-ear model that boasts just as much refinement and quality as the larger and slightly more expensive MH40 - like a solidly built forged aluminum frame with beautifully designed details, detachable woven audio cables with built-in audio controls, a durable cowhide leather covered headband and detachable memory foam ear pads covered in supple lambskin leather. Unlike the MH40, the MH30's portable design allows them to be folded for more convenient carry. And while the MH30 are made using the same premium materials and general design aesthetics as Master & Dynamic's MH40, on the inside, the MH30 in fact have smaller 40mm Neodymium drivers versus the 45mm drivers found in the MH40. So you're thinking about a pair of Master & Dynamics and still need help deciding which one to get? We've made it easy for you.
