Today finds Master & Dynamic adding two new headphones to its rapidly growing family of products. The new MH40 Over Ear Headphones and MH30 On Ear Headphones come in either silver metal/white leather and gunmetal/black Alcantara editions. The silver/white models add light grey hits to the ear pads and headband lining, while the gunmetal/black colorway utilizes Alcantara, a unique made in Italy material used on the headband, ear cups and ear pads. (It should be noted, Alcantara also has the added benefit of keeping the ears warm as the temperatures dip.) The MH40 Over Ear and Headphones ($399) and MH30 On Ear Headphones ($329) are available now at Master & Dynamic's online store.
