The reference-class Sennheiser HD 800s is a modern classic, rendering sound that is natural and true to the least detail - offering the most accurate sound possible.  While it's no easy task to improve on an already-perfect formula, Sennheiser's engineers took the success of the original HD 800 even further, enhancing sound reproduction to its final limit in the open, circumaural HD 800s.  Striking industrial design renders form and function in eye-arresting symbiosis, seamlessly layering metal and plastic to offer vibration-attenuating headband and earcups.  Handmade microfiber earcups offer long-lasting comfort sure to hold up against even the longest, most-demanding listening sessions.  Exactingly crafted to perfection, the HD 800s is precision-built in Germany from only the finest materials and components.  A steel-encased transducer is complimented by a headband and headphone mounting that utilizes the most advanced materials developed in the aerospace industry for high strength with minimal weight.
