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