Sennheiser HD 820 High-end Headphones

Description

Founded in 1945, the German brand Sennheiser is synonymous with quality. During the last half century they have basically produced three things: headphones, microphones and telephone accessories. More than half a century of experience later, Sennheiser has created what many consider the best closed headphones in the world. Put it simply: The HD 820 are the closed headphones with the most transparent sound ever created.

With these groundbreaking closed dynamic headphones passionate music lovers can now enjoy their music at an audiophile level wherever they please, at home or on the move. Featuring unique glass transducer covers that minimize resonances, the HD 820 are simply the most transparent-sounding closed headphones in the world, extending the boundaries of what has been achieved in sound reproduction with closed type headphones up to now.

For audiophiles there wasn’t any doubt: When it came to circumaural headphones the very best sound required an open back design. 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.

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.

Vivid, wide, transparent, natural. The sound field of the HD 820 is wide open. 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.
