  • Sennheiser HD820

    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.

    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.
