Which is not what you would expect at all from closed circumaural headphones. With the HD 820 you can explore and rediscover your music in absolute reference-class quality without intruding on the aural comfort zone of others. Thus, the HD 820 not only open up the sound field, but also new places and opportunities for you to enjoy your music. The Technology of Transparency The breakthrough transparent performance of the HD 820 has been achieved through a special innovation: Their legendary Sennheiser Ring Radiator transducers are fitted with unique glass covers. Revealing the great look of the technical component within, this visually striking feature was actually developed wholly in service to the sound: The concave glass reflects the sound waves from the rear of the transducer to an absorber, which results in minimal resonance. Thus, the sound waves are effectively gone like they would be in open headphones.

This axiom has now been rendered obsolete by the youngest member of the Sennheiser Audiophile Range: The closed dynamic HD 820 employ an innovative technology that makes them sound breathtakingly transparent and natural. Developed and made in Germany, they offer an incredibly realistic, natural sound field and also stand apart by the extraordinary attention given to every detail of their design. Their soft comfortable microfiber ear pads are hand crafted, providing excellent attenuation of ambient noise, while the robust metal headband includes an inner damping element. Get ready for an unparalleled listening experience. Developed and manufactured in Germany, the HD 820 is a closed, reference-grade audiophile headphone that a combines an innovative glass reflector and Ring Radiator transducer technology for a benchmark listening experience as vivid as it is uninterrupted. The HD 820 fuses Sennheiser's bleeding-edge acoustic capabilities with exceptional reduction of ambient noise. Until now, the audiophile headphone experience could only begin with an open back design or loudspeakers. The HD 820 sacrifices neither detail nor sound field by using breakthrough acoustical systems in a closed, dynamic headphone. The reference-class experience of the HD 820 is achieved with the use of precision concave glass reflectors, one capping each earcup. These functional plates reflect energy from the rear of the driver to a specially tuned absorber system, allowing the waves to mimic the behavior of open headphones such as the HD 800 S. The result is a sound stage never before experienced in a sealed headphone. The headphone’s vibration damping headband provides complete stability while reducing crosstalk. What you put into the HD 820 is precisely what you will get out of it. Each transducer is manufactured, tested, and measured to an extremely tight tolerance to ensure the most dependable performance out of the box. Each HD 820 also includes the frequency response plot unique to that set’s serial number, sparing no resource to help you retrieve the most critical details from every corner of your music collection. The 56mm Ring Radiator transducer found in the HD 820 leverages the key benefit of a large diaphragm speaker—air displacement. Both outer and inner edges of the “ring” are secured to the drive unit to keep it rigid for fast rest and response times. The result is accurate response spanning the entire frequency spectrum.
