Description

The HD 820 combines the renowned cutting-edge technology of our transducer with an exceptionally high attenuation of ambient noise that far exceeds all expectations of closed headphones. Until now, Sennheiser has relied on the concept of an open headphone in favor of maximum sound experience. This concept, consistently implemented in design, paved the way for a whole series of high-quality, precision-designed headphones. The standard developed here in terms of sound reproduction could even prevail over much larger and more expensive hi-fi systems and also offered the advantage of independent location. The HD 820 combines equal attention to detail with a focus on unique sound. The result is the consistent implementation of an innovative acoustic system into a closed, dynamic headphones.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $414 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Sennheiser products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
