Sennheiser HD 820 Sealed Back Headphones
Sennheiser HD 820 headphones are the perfect blend of innovation, quality, and design. With its high resolution audio these closed-back headphones offer an immersive audio experience. An updated, fresh new look, and an even more natural sound that reveals the absolute finest of music details. 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.
Key Features
This is the first sealed-back model in Sennheiser’s legendary HD 800 series, and the company went all out. The earcups are sealed with concave, heavy-duty glass covers that show off the drivers and help absorb unwanted vibrations. The result? Transparent, spacious sound like you’d expect from an open-back headphone, but with the insulated listening experience of a closed-back design.
As a centerpiece of your constantly evolving rig, your go-to headphones should offer the versatility to listen on your terms. Your HD 820 comes with a versatile set of essential cables, each one impedance-matched with ultra-low capacitance. The ¼-inch / 6.3mm stereo connector offers the audiophile-standard plug for connection to devices such as headphone amplifiers, DACs, and A/V receivers. A balanced 4.4mm connector opens a pathway to a newer generation of balanced output devices (headphone amplifiers, digital audio players, etc.) that embrace this compact plug’s superior stability over time. An optional XLR-4 balanced cable is available, providing yet another popular connection to a wide range of audio components. Each cable is 9.8ft / 3m long to accommodate unencumbered listening from devices anywhere on your shelves, in your studio, or on your desktop.
