At €90, this used Sennheiser HD 25 is a fair deal that sits just below the median of €91 from our recent EUR listings, making it a solid choice over cheaper, flimsier alternatives in this price band. It’s not a bargain by the percentile standards (25th at €85, 75th at €100), but it’s priced right for a clean, working unit in unknown condition.
The HD 25 is a legendary club and DJ headphone known for its rugged build, 70-ohm impedance that works well with both pro gear and mobiles, and precise sound across 16–22,000 Hz. Its 120 dB max SPL means it handles loud environments without distortion, and the detachable cable adds long-term value. If the unknown condition turns out to be good and the cable is intact, this is a worthwhile buy for anyone needing durable, no-nonsense audio.

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.
