Sennheiser HD 820
Sennheiser's flagship closed-back audiophile headphone, using the same 56mm ring radiator drivers as the open-back HD 800 S but paired with concave Gorilla Glass earcup covers that redirect rear driver energy to a built-in absorber. Delivers a remarkably open, spacious soundstage for a closed-back design while offering up to 26 dB of passive isolation.
Our Verdict
Sennheiser's flagship closed-back with 56mm ring radiator drivers and Gorilla Glass reflector technology. Delivers remarkably open soundstage for a closed-back design with up to 26 dB isolation.
