Sennheiser HD820 Headphones + HDV820 Headphone Amplifier

A benchmark listening experience as vivid as it is uninterrupted.

The new audiophile standard

The critics said closed headphones could never sound as immersive as their open-air counterparts. They said physics would never allow it. To that, we simply said, “listen”. The HD 820 combines an innovative glass reflector and ring radiator transducer technology for a benchmark listening experience.

Exhaustive engineering

The deep, almost magical stereo imaging of the HD 820 is the sum of the exhaustive engineering poured into it.

Developed in Germany and crafted at our state-of-the-art Ireland plant, its fit and finish is second only to its sound quality. When combined with the ring radiator’s superlative response, the driver’s angle allows you to locate voices, instruments, and their inherent environments. The sound field expertly balances realism and escapism, transporting you to the heart of your favorite recordings and nowhere else. The luxurious ear padding and progressive articulation points form a satisfying seal, eliminating distractions for added focus during extended listening sessions. For critical listening tasks and private listening alike, the HD 820 prevents unwanted sound from coming in or bleeding out.

Completely closed. Outrageously open.

The HD 820 fuses our cutting-edge transducer capabilities with exceptional ambient noise attenuation, transcending the perceived limits of closed headphones. 

Reflecting within

A closed-back headphone able to produce the wide, natural sound field of an open one requires rethinking the directional characteristics of sound waves.

Fellowship of the Ring

An achievement in its own right, the 56mm ring radiator found in the HD 820 leverages the key benefit of a large diaphragm transducer—air displacement—without losing the rigidity that favorably impacts rest and response times.
