I'm David Karl away from cnet.com and this is the M 840 a beautifully crafted Kolkata dollar headphones from a new new york-based company called master and dynamic is forged from aluminium stainless steel and real lambskin leather and its sound is competitive with that of comparable priced models from established brands like AKG bear dynamic Bowers & Wilkins and Sennheiser the MH 40 is a closed back over the ear design with 45 millimeter drivers and a 32 ohm rated impedance weighing 12 point 7 ounces or 360 grams it's definitely heavier than most over ear headphones the upside is the MH 40 s build quality feels super solid and the supple leather adds a sensual side to the design the headphone comes in a few different color options beyond the tan and silver version you see here terms of accessories you get a simple canvas carrying bag in a small case for the two included cables a one point two five meter one with a remote and mic for iOS devices and a 2 meter plain cable this is a passive headphone and the noise isolation is decent and we liked how the right ear cup has a metal mute button that indeed mutes the sound when you press it the headband isn't hinged but the ear cups do fold flat for storage that's worth noting that the warranty coverage is two years or double what most headphone brands offer performance wise the MH 40s and is highly detailed yet never harsh and the bass is deep without any boom or bloat it's not quite as strong in the mid-range vocals could be a little richer but overall this is an excellent sounding headphone that stacks up well against other audiophile headphones in the 300 to 400 Ava car noise and that's the master and dynamic MH 40 thanks for watching
