About KOSS CORP

Koss Corp. (ticker: KOSS) is a U.S.-listed micro-cap company trading on the NASDAQ in the United States, focused on consumer audio. Founded in 1958 by John C. Koss in Milwaukee, Wisconsin, the company built its identity around inventing the first consumer stereophone, the SP/3. That heritage remains a core part of the brand story: Koss presents itself as a long-standing specialist in personal audio, with its business centered on the design, manufacture, and sale of stereo headphones and related accessories. ([koss.com](https://koss.com/pages/support?utm_source=openai)) Operationally, Koss offers a compact but fairly broad product portfolio for a small audio company. Its lineup includes high-fidelity headphones, wireless Bluetooth headphones, wireless Bluetooth speakers, computer headsets, telecommunications headsets, and active noise-canceling headphones. The company sells under the Koss brand and, in some cases, private-label arrangements. Distribution is multi-channel and includes U.S. and international distributors, audio specialty stores, e-commerce, national retailers, electronics chains, grocery channels, educational customers, prisons, and OEM customers. In addition, Koss serves direct-to-consumer demand through its website and online marketplaces.

Its competitive strengths are its long operating history, brand recognition in stereophones, and the breadth of its channel mix across consumer, institutional, and OEM segments. The company reports itself as a single operating segment, which underscores how concentrated the business remains on personal listening products. Geographically, Koss has a meaningful international footprint despite its modest size: it sells into Europe, the Middle East, Africa, Asia, Australia, Latin America, the Caribbean, Canada, and Mexico, with sales personnel located in the Netherlands and the Caucasus region to support export markets.

In fiscal 2025 and into fiscal 2026, Koss reported modest revenue growth, with export sales and direct-to-consumer momentum helping offset weaker domestic distributor demand. Management also highlighted tariff pressure tied to China-sourced products, which is an important margin headwind. In March 2026, the company announced the hiring of a Director of Acquisitions and Corporate Development, suggesting that Koss is exploring expansion opportunities beyond its historical core. For French-speaking investors, the key takeaway is that Koss remains a specialized U.S. NASDAQ-listed headphone maker with a distinctive brand legacy, a narrow product focus, and a small-cap risk profile influenced by tariffs, channel mix, and competitive pressure from larger audio brands.
