Sennheiser’s HD 820 up against a window

Announced at the beginning of CES, Sennheiser’s HD 820 are closed-back dynamic stereo headphones that, according to Sennheiser, reproducing “astonishingly transparent sound” due to a unique glass transducer that works to minimizes resonance.

Sennheiser promises “incredibly realistic” and “natural” sound when using the HD 820. This is said to be achieved with the headphone’s glass covers that overlay the headphone’s Ring Radiator transducers. Inside, the curved Gorilla glass reflects the sound waves from the rear of the transducer to two absorber chambers, which should result in minimal resonance.

The headphones feature a metal headband with an inner damping element, and silver-cladded OFC cables and gold-plated plugs. Their ear pads are crafted from non-allergenic synthetic leather and microfiber that “cushion and insulate the listener from ambient noise.”

Sennheiser truly believes that the HD 820 will be pushing what is possible in sound quality for the closed-back design.

“Whether on the move, at work or at home, the passionate audiophile will always want to appreciate their music to the fullest,” said Axel Grell, Portfolio Management Consumer at Sennheiser. “Usually, high-end headphones require an open-back design, which has placed limits on where you can enjoy true audiophile sound. 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.”

You’ll be able to get the HD 820 this early summer for $2,399. You can learn more about these headphones at Sennheiser.com.
