The new Sennheiser HD 820 is a circumaural dynamic stereo headphone design that the German company says shatters expectations of “what was thought possible from a closed-back model and set a new benchmark in sound quality for this type of design.”
“Whether on the move, at work or at home, the passionate audiophile will always want to appreciate their music to the full. 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,” says Axel Grell, Portfolio Management Consumer at Sennheiser.
According to Sennheiser, the HD 820 performance has been achieved through a special innovation: Over each of the legendary Sennheiser Ring Radiator transducers are unique glass covers. Revealing the acoustics within, the patent-pending curved Gorilla glass serves to reflect the sound waves from the rear of the transducer to two absorber chambers, which results in minimal resonance.
Otherwise, the Germany-manufactured headphones feature a robust metal headband with an inner damping element, and silver-cladded OFC cables and gold-plated plugs. The ear pads are handcrafted from high-quality non-allergic synthetic leather and microfiber to cushion and insulate the listener from ambient noise.
The new HD 820 will be available from early summer 2018 for 2,399 EUR/2,399.95 USD (MSRP).
