Sennheiser HD820 Headphones
This new HD820 closed back model sits above HD800 and HD800S offering music-lovers audiophile level sound whether they are at home or on the move.
Sennheiser HD820 closed dynamic headphones are designed for passionate music lovers, allowing them to enjoy audiophile grade audio wherever they please, at home or on the move.
Featuring unique glass transducer covers that minimise resonances, the HD820 is simply the most transparent-sounding closed headphones in the world surpassing the boundaries of what has previously been achieved with closed type headphones.
New Audiophile Standard
Typically, when it came to circumaural headphones the very best sound required an open back design. This axiom is now rendered obsolete by the youngest member of the Sennheiser Audiophile Range; The closed dynamic HD 820 employs an innovative technology for breathtakingly transparent and natural sound.
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 handcrafted, providing excellent attenuation of ambient noise, while the robust metal headband includes an inner damping element.
Into the Great Wide Open
Vivid, wide, transparent and 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.
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.
HD 820 stands apart due to the extraordinary attention 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 unparalleled listening experience can even be improved by the Sennheiser HDV 820 amplifier for dynamic headphones, the perfect companion to the HD 820.
Only what gets in can eventually get out. That’s why the HD 820 come with a specially tuned symmetrical, impedance-matching cable with low capacitance and a balanced 4.4mm gold plug, which offers superior characteristics in contact resistance, and thus in sound.
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.
