It’s a buyer’s market for this category, and this ask is ambitious: €150 sits well above the €130 75th percentile and far above the €35 median for recent comparable listings. At that level, it needs something exceptional to justify it, so the price only makes sense if there’s unusual condition, a standout bundle, or some collectible angle not shown here.
The upside is that this model is widely liked for its light comfort, easy driveability, and lively, surprisingly open sound for the money. That makes it a fun everyday pickup, but at €150 the value case depends heavily on what’s included and whether the condition is truly excellent; otherwise, a buyer should wait for a more typical ask.
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.
