A modern classic, Sennheisers reference class HD 800 headphones deliver sound that is as natural as possible and true in every detail. Improving on a seemingly perfect formula is not a task undertaken lightly, but Sennheisers engineers have succeeded in enhancing still further the sound reproduction in the open, circumaural HD 800 S. 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. The new HD 800 S offers even better high precision connectivity options and is now supplied with two connection leads, a 6.3mm connector and a XLR-4 balanced Cable to offer even better quality sound from sources with balanced outputs such as the Sennheiser HDVD 800 headphones amplifier. 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 a breakthrough that preserved the audibility of very high frequency sounds by eliminating a phenomenon known as the masking effect, where the human hear 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, Sennheisers patented absorber technology prevents any unwanted peaks and allows all frequency components even the finest nuances in the music material to become audible. This innovation was a key element in making the IE 800 the worlds best sounding in ear headphones.
