 Description of Sennheiser HD 820 earphones

The Sennheiser HD 820 closed reference headphones head the audiophile line of high-end full-size stereo phones in the Sennheiser lineup.


The model has an original innovative design, which involves the use of transparent glass domes-deflectors built into the back of the cups, which "catch" sound waves emitted by the back of large drivers with an annular membrane, and reflect them into special absorbing chambers. As a result, it is possible to minimize resonances and achieve the same effect as in open headphones, where the sound waves emitted by the back of the speakers go into the surrounding space. According to Sennheiser, this technology dispels the myth that closed stereo phones can't provide the same natural, transparent sound with a wide, deep stage as their open counterparts.


The industrial design of the Sennheiser HD 820 impresses with its exquisite refinement, which is in no small part facilitated by the domed glass deflectors made of durable Gorilla Glass. Much attention has been paid to comfort. The thick, hand-crafted ear cushions are made from a special microfiber material that limits outside noise while providing excellent sound isolation. Microfiber is very practical and cleans well. In addition, perspiration will not form in such ear pads. The headband is made of metal/composite and is equipped with a damping element.

The headphones are equipped with two straight, double-sided detachable cables with OFC silver-plated copper conductors. One of them is terminated using a 6.3 mm jack, the second is terminated using balanced Pentaconn connectors (4.4 mm), and a cable with XLR-4 connectors is an optional purchase. The kit includes a USB flash drive with instructions and a graph with the frequency response of a particular headphone instance. Includes microfiber cloth and storage box.


The company emphasizes that, thanks to innovative technologies, the Sennheiser HD 820 headphones are able to sound transparent, natural and realistic, while providing a wide-open soundstage. The HDV 820 Headphone Amplifier is the ideal option to unlock the full potential of this flagship.
