■Overwhelming sense of openness
・The HD820 uses an innovative sound system to achieve an overwhelming sound field that exceeds that of open headphones even though it is a closed headphone, without sacrificing detail or sound field.


■Natural and expansive sound field
・HD820 is equipped with Sennheiser's ring radiator transducer with a unique glass cover. Not only is it visually captivating to see the intricate technical components inside, but they're also engineered to deliver great sound. The concave glass reflects the sound waves emitted from the back of the transducer back to the absorber, minimizing echoes.
