Closed-back audiophile reference headphones with 56 mm ring radiators and Gorilla Glass reflectors
The Sennheiser HD 820 are closed-back reference headphones for audiophiles, bringing the spacious, natural sound of high-end open-back headphones to a design that isolates you from your surroundings. They are made for listeners who want top-tier sound without disturbing others or being disturbed by room noise.
56 mm ring radiator transducers, concave Gorilla Glass reflectors, 6 Hz – 48 kHz response and 6.35 mm and 4.4 mm balanced cables.
Open-back sound in a closed design
The HD 820 use the same 56 mm ring radiator transducers as the HD 800 S. The challenge was to keep the sound spacious and natural despite closed ear cups. Sennheiser's solution is concave Gorilla Glass reflectors that direct the sound from the rear of the transducer into small absorber chambers and reduce resonances.
Isolation without compromise
The closed-back design keeps the sound in and noise out, so you can enjoy audiophile quality anywhere, even with others next to you. With response from 6 Hz to 48 kHz and distortion below 0.02%, they reproduce every detail of the recording.
High-end construction
A metal headband with internal damping and microfiber ear pads provide comfort for hours. The package includes 3 m cables with 6.35 mm and balanced 4.4 mm plugs, a storage case and a cleaning cloth. With 300-ohm impedance, they pair ideally with a quality headphone amplifier.
