The striking industrial design combines form and function seamlessly, the layered metal and plastic headband construction attenuating vibrations to the earcups while the handmade microfiber earpads offer exceptional comfort for even long periods of listening enjoyment.

Crafted for perfection, the HD 800 and the HD 800 S are precision-built in Germany from only the finest materials and components. The transducer is encased by stainless steel, while the headband and headphone mounting utilises the most advanced materials developed in the aerospace industry for high strength with minimal weight.

**Absorber technology of the HD 800 S**
The enhanced sound reproduction of the HD 800 S is achieved through the addition of the innovative absorber technology that was pioneered in the Sennheiser IE 800 â€“ a breakthrough that preserved the audibility of very high frequency sounds by eliminating a phenomenon known as the â€œmasking effectâ€, where the human ear struggles to hear frequencies of sound when lower frequencies of a higher volume occur at the same time. By absorbing the energy of the resonance, Sennheiserâ€™s patented absorber technology prevents any unwanted peaks and allows all frequency components â€“ even the finest nuances â€“ in the music material to become audible. This innovation was a key element in making the IE 800 the worldâ€™s best sounding in ear headphone, and in the HD 800 S it helps to bring even greater purity and precision.

Such enhancements build on the formidable achievements of the classic, with the 56mm sound transducer â€“ the largest ever used in dynamic headphones. The unique ear cup design directs sound waves to the ear at a slight angle to create an impressively natural and spatial listening experience.

While much appears the same, the enhanced performance within is revealed by a distinctive new look, with the silver finish of the 2009 classic HD 800 making way for high-class matt black for the HD 800 S.
