Sennheiser HD 820 Closed-Backed Audiophile and Reference Headphones

The Future of Audio

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.

Into the great wide open

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.

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.

Superior Quality Build

Made in Germany, the HD 820 stand apart also because of the extraordinary attention that is given to every detail: From the extra comfortable handcrafted ear pads that insulate the listener from ambient noise, to the silvercladded OFC cables and gold-plated plugs, to the robust metal headband with an inner damping element. A well-conceived audio component always looks good – inside and out. With their unique glass covers the HD 820 display all the evidence to prove this. They are an aesthetical timeless classic and a natural technical beauty.
