HD 820

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.

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.
