A New Audiophile Standard for Closed-Back Headphones
With Sennheiser's groundbreaking HD 820 closed dynamic headphones, passionate music lovers can now enjoy their music at an audiophile level wherever they please, at home or on the go. Featuring unique glass transducer covers that minimize resonances, the HD 820 are one of the most transparent-sounding closed headphones in the world, extending the boundaries of what has been achieved in sound reproduction with closed type headphones.
For audiophiles, when it came to circumaural headphones, the very best sound required an open back design. But now that's changed. The closed dynamic HD 820 employ an innovative technology that makes them sound breathtakingly transparent and natural. Developed and made in Germany, the HD 820 offers an incredibly realistic, natural sound field and also stands apart by the extraordinary attention given to every detail of the design. The 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.
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. The innovative 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.
An All-Star Team of Excellent Components
Made in Germany, the HD 820 stands 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, and to the robust metal headband with an inner damping element. This package offers an unparalleled listening experience, which can only be improved by pairing the HD 820 with the Sennheiser HDV 820 amplifier for dynamic headphones.
Audiophile Connectivity
Even the cable is special. The HD 820 comes with a specially tuned symmetrical, impedance-matched cable with low capacitance and a balanced 4.4 mm gold plug, which offers superior characteristics in contact resistance, and thus in sound.
The Look of Superior Quality
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.
