Sennheiser HD 820 Closed-back Audiophile Headphones - Sennheiser
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
The HD 820 fuses our cutting-edge transducer capabilities with exceptional ambient noise attenuation, transcending the perceived limits of closed headphones. The HD 820 sacrifices neither detail nor sound field thanks to its innovative acoustical systems in a closed, dynamic headphone. The headphone’s vibration-damping chassis and inert headband insert provide complete stability, resulting in astonishing speed and accuracy throughout the entire frequency spectrum.
The 56mm ring radiator found in the HD 820 leverages the key benefit of a large diaphragm transducer air displacement without losing the rigidity that favorably impacts rest and response times. Instead of a single attachment on the outer circumference of the transducer, both outer and inner edges of the 'ring' are secured to the drive unit. The voice coil vibrates the diaphragm, connected to the V-shaped groove found near the center of the ring.
The HD 820 delivers on long-term wearing comfort too, providing a listening experience as plush as it is immersive. Every contact point utilizes ultra-soft padding, while purpose-built composites reduce weight and unwanted pressure. Each earcup provides dual-axis articulation that instantly and effortlessly conforms to your head’s unique structure. The result is a listening session that never gets in the way of your passion for hi-fidelity sound reproduction.
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.
