The Sennheiser HD-820 is a closed-back version of the legendary HD800 headphones, and uses some innovative technology that makes them stunningly transparent.
Closed-back designs have historically suffered from unwanted resonances, while open-back designs, famed for their natural, transparent sound, can leak audio and let in ambient sounds.
For the HD-820, Sennheiser have used a glass outer cover paired with internal absorbers to eliminate resonances, giving audiophile listeners the best of both worlds.
Sennheiser's Axel Grell, Chief Headphone Engineer, says:
"The HD 820 is a game changer that delivers exceptional sound while insulating the listener from their environment. I consider them to be the most transparent-sounding closed-back headphones in the world."

New HDV-820 Headphone Amplifier
This ultimate performance is completed by Sennheiser’s new HDV 820 amplifier for dynamic headphones. With its symmetrical signal processing and extremely low harmonic distortion, it ensures unadulterated and perfect music enjoyment when paired with audiophile headphones.
A specially tuned symmetrical, impedance matching cable with low capacitance is included with the HD 820 to guarantee seamless performance from this audiophile duo.
The HD 820 as well as the HDV 820 have connectors according to the new standard for balanced outputs: the Pentaconn connector. This connection has a lower contact resistance than all other connections for headphones producing minimal distortion and a more transparent sound reproduction.
The recommended retail price of the HDV820 headphone amplifier is $3,799.
