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.
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 withinA 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 RingAn 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.
