Offered is „HD 800 S“ by Sennheiser as second-hand device from the category „Wire bound Headphone“ on audio-markt.de - the online market place for high-end. The advert with the number 3892130424 ends on 14.11.2026 at 13:19 o'clock.
This is a flagship-style headphone with a serious reputation, but the asking price is well above the recent used market anchor. At €750, it sits far past the 75th percentile of €251 and looks ambitious rather than merely fair against a median of €85.
That doesn’t make it a bad headphone, just a price that needs strong justification: pristine condition, original packaging, fresh pads, documented care, and ideally recent servicing. The appeal is the HD 800’s huge stage, pinpoint imaging, and resolving presentation, which still make it a benchmark for open-back listening, but the value here depends heavily on completeness and condition.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
