Sennheiser HD 820 Closed-Back Headphones

Closed-back and open-back headphones both have their advantages. One blocks out external noise and extends bass frequencies; the other releases internal audio for a more expansive soundstage. Historically, it’s proven near impossible to get these benefits all at once—but in the new HD 820 headphones, Sennheiser has made it happen. On the outside, the HD 820 features a closed-back case for impressive isolation and bass extension. Inside, Sennheiser's beloved Ring Radiator drivers use glass covers to reflect sound waves into an absorber, where they effectively “vanish,” creating a vivid soundstage that feels wide open. Made in Germany, the HD 820 also features OFC cables and gold-plated plugs, handcrafted earpads, and a robust metal headband with an inner damping element for extra comfort, strength, and sound fidelity.
