The evolution of the legendary classic

With the development of the open dynamic HD 800 S headphones, the engineers at Sennheiser have achieved the impossible: they have further enhanced the exceptionally natural sound reproduction of the standard-setting HD 800 reference headphones. The striking industrial design combines form and function seamlessly, the layered metal and plastic headband construction attenuating vibrations to the ear cups while the handmade microfiber ear pads offer exceptional comfort for even long periods of listening enjoyment. The HD 800 S is precision-built in Germany from only the finest materials and components. The transducers are encased by stainless steel, while the headband and headphone mounting utilizes the most advanced materials developed in the aerospace industry for high strength with minimal weight.
