The undisputed outstanding sonic quality of the B & O A8 Headphones already adequately described in the other reviews. So I will confine myself to the functional qualities of these headphones. First, one is struck by the unusual design. Made entirely of aluminum make the headphones very high-quality impression. The rubberized straps are fastened with a screw also made of aluminum, so that the durability of this design can be considered as durable. In general, the straps are designed so that they act even for me as eyeglass wearers during long listening not disturbing. The supplied foam pads support the wearing comfort while significantly. Not should also be mentioned that the gentlemen from Denmark mitliefern a chic cover for transporting the head higher. For if a (sound) artworks simply suspend the profane influences of the environment, would be a sacrilege.
