Master & Dynamic is a relatively new professional audio company that produces some high quality audio products for high end users. The Mastser & Dynamic MH40 over-the-ear headphones sport 45mm drivers, real leather and metal construction, and some great accessories that would fit the bill for a DJ or producer's performance and lifestyle needs. The MH40's come bundled with two different cables (one with an in-line mic and remote and a straight cable without), that are both wrapped in durable fabric material. The MH40 headphones also come with a durable canvas carry bag for transport and storage. They MH40 come in a variety of different color options and they are advertised as being built from the finest materials while also being very durable for performances or transport. We're working on the full video review, but we've finished the unboxing and first impressions video to show you all that comes in the package.
