Angeboten wird „HDV 820“ von Sennheiser als Gebrauchtgerät aus der Kategorie „Kopfhörerverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 6596689978 endet am 15.08.2026 um 14:28 Uhr.
At €990, this lands below the €1,055 median and just over the €886 25th percentile, so it reads as a solid fair-to-good buy rather than a bargain-basement steal. It is well under the €1,314 75th percentile, which keeps it comfortably on the buyer-friendly side of the market.
The HDV 820 is a respected all-in-one DAC/headphone amp with serious headroom, clean measurements, and enough drive for demanding headphones; Sennheiser’s own current new price is €2,699, so a clean used unit at €990 preserves a lot of value. If the listing includes the original box, power supply, and remote, that pushes it further into “worth jumping on” territory; at this price, I’d mainly want confirmation that all inputs and the display work properly.

Founded in June 1945 by Dr. Fritz Sennheiser in a farmhouse near Hanover, Germany, Sennheiser began as Laboratorium Wennebostel, producing voltmeters and early microphones amid post-World War II reconstruction. Seven engineers from the University of Hannover joined the founder, quickly pivoting to broadcast microphones like the DM 2 in 1946 and the groundbreaking MD 82 shotgun mic in 1956. Renamed Sennheiser electronic in 1958, the family-owned company passed to second- and third-generation leadership, maintaining its innovative spirit over eight decades.
Sennheiser excels in professional and consumer audio, renowned for microphones, wireless systems, and headphones that set industry standards. Pioneers of the first open-back headphones (HD 414 in 1968) and enduring studio icons like the MD 421 and MD 441, they also produce high-end headphones, earbuds, soundbars, and conferencing solutions. While strong in pro audio like mixers and geophysical gear, their consumer focus centers on headphones and wireless tech rather than amplifiers, speakers, turntables, DACs, or cables.
Sennheiser commands a premium position in the hi-fi market, blending mid-tier accessibility with high-end excellence for discerning buyers and professionals. Trusted for reliability and sonic precision, it appeals to audiophiles seeking reference-grade headphones without boutique obscurity, backed by a heritage of technological firsts that sustains its global leadership.
