Sennheiser’s HD 820 set a benchmark for audiophile sound quality for closed back dynamic stereo headphones. They feature an innovative glass transducer cover that minimizes resonances. This unique design ensures an incredibly realistic and natural sound field, making them the most transparent- sounding closed headphones in the world.

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.

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.

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 silver cladded OFC cables and gold-plated plugs, to the robust metal headband with an inner damping element.

This package offers an unparalleled listening experience, which can even be improved by the Sennheiser HDV 820 amplifier for dynamic headphones – the perfect companion to the HD 820.
