What KOSS CORP does
In the company’s own words
Koss Corporation (Nasdaq: KOSS) operates in the audio and personal listening industry through the design, manufacture, and sale of stereo headphones and related accessory products. The company maintains its website at https://www.koss.com.
Founded by John C. Koss, who created the first personal stereo headphone, the SP/3, in 1958, Koss has established itself as a pioneer in the personal listening industry. The company holds approximately 400 trademarks registered across approximately 88 countries worldwide and maintains nearly 170 patents in approximately 25 countries, reflecting its significant intellectual property portfolio. These trademarks and patents serve as key differentiators in the competitive stereo headphone market.
The company operates as a single reporting segment focused exclusively on stereo headphones and related personal listening accessories. Approximately 80 percent of fiscal 2026 sales derived from stereo headphones used for music listening, with the remaining 20 percent from headphones used in communications, education settings, metal detector applications, and original equipment manufacturer sales. The company sources complete stereo headphones and raw materials from various manufacturers in Asia, with over 90 percent of products manufactured by contract manufacturers in China and Taiwan. The company maintains a manufacturing facility in Milwaukee, Wisconsin, where it also stocks finished goods inventory.
Koss distributes its products through multiple channels including U.S. distributors, international distributors, audio specialty stores, national retailers, grocery stores, electronics retailers, and direct-to-consumer sales via online marketplaces. International markets are served through domestic sales representatives and personnel located in the Netherlands and the Caucasus region. The company's largest sales concentration comes from direct-to-consumer offerings through the Amazon portal, representing approximately 22 percent of net sales in fiscal 2026.
As of June 30, 2026, the company employed 30 employees. International sales represented approximately 17 percent of consolidated net sales, with the company maintaining a global presence across North America, Europe, Asia-Pacific, Latin America, and other international markets. In March 2026, the company announced a diversification strategy through acquisitions of other businesses to expand beyond the consumer electronics space and generate predictable, recurring revenue streams.
