At €150, the timing only matters if you specifically want this old Koss behind-the-head design; otherwise the market is clearly cooler than the ask, with recent comps centered much lower at €35 and only the upper quartile reaching €131. That puts this listing above the 75th percentile, so it reads as ambitious rather than a buy-now bargain.
What keeps it interesting is that Koss’s lightweight clip-style and behind-the-head comfort have a loyal following for casual listening and swap-friendly vintage use, especially if you want an intact, original set. Still, at this level the condition and completeness matter a lot: make sure the drivers work evenly, the headband tension is still good, and any original pads or accessories are included, because the price leaves little room for missing parts or tired hardware.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Koss Corporation traces its roots to 1953 in Milwaukee, Wisconsin, where founder John C. Koss launched the J.C. Koss Hospital Television Rental Company with just $200, repairing and renting TVs to patients. The pivotal shift came in 1958 when Koss, partnering with engineer Martin Lange Jr., invented the world's first high-fidelity stereo headphones—the SP/3 stereophone—as part of a portable phonograph. This breakthrough birthed personal stereo listening, catapulting the brand from a modest TV rental outfit to an audio pioneer with deep Midwestern heritage.
Koss specializes in headphones, from its iconic full-size Pro/4AA professional models introduced in 1970 to the enduring Porta Pro portable headphones launched in 1984, which blended superior sound, comfort, and lightweight design. While not venturing into amplifiers, speakers, turntables, DACs, or cables, the brand has consistently focused on dynamic, noise-isolating headphones that prioritize musical fidelity over fleeting trends.
Renowned for its vintage appeal and collector status among hi-fi enthusiasts, Koss occupies a niche mid-tier position, emphasizing timeless engineering and value-driven performance rather than high-end luxury or mass-market flash. Its family-owned structure—controlled by the Koss family—and Milwaukee roots underscore a commitment to authentic audio heritage, sustaining loyalty in a market dominated by coastal giants.
