Customers
Koss sells to a mix of distributors, retailers, online marketplaces, and OEM customers, with direct-to-consumer sales also playing a meaningful role. The company’s products are bought by consumers for music, home office, study, and communications use, while commercial buyers use Koss products for resale or inclusion in their own offerings. Customer concentration is important: the company disclosed that its largest sales concentration was DTC via Amazon, and its five largest customers represented a large share of net sales.

Purchase headphones and headsets for resale through mass merchants, specialty stores, electronics stores, and grocery channels.
Buy products for resale across Europe, the Middle East, Africa, Asia, and the Americas to extend market reach.

Strategy
Management is focused on increasing sales in the U.S. distributor market, direct-to-consumer channels, and export markets. The company is also emphasizing new product introductions, cash generation from operations, and tighter inventory and capital spending discipline to support liquidity and earnings. These priorities fit a small consumer audio business that depends on channel access, product refreshes, and working-capital control.
Broader channel penetration supports volume and product placement in a crowded audio market.
DTC can improve brand control and reduce reliance on third-party shelf space.
Product refreshes help offset customer churn and shifting preferences toward wireless audio.
Working-capital discipline is important for a small manufacturer with customer concentration.
Geography
Koss is headquartered in the United States but sells domestically and internationally through distributors, retailers, and online channels. The company has sales personnel in the Netherlands and the Caucasus region and uses independent distributors across Europe, the Middle East, Africa, Asia, Australia, South America, Latin America, the Caribbean, Canada, and Mexico. Management also noted that Europe represents a material portion of sales and profits, making currency movements and trade barriers important to performance.
Risks
Koss faces customer concentration, channel dependence, and competitive pressure in a market where product mix and pricing can change quickly. Its international exposure adds tariff, currency, and geopolitical risk, while supply-chain disruptions and cyber incidents can interrupt sales, fulfillment, and data security. Accounting estimates around inventory, warranty obligations, returns, and credit losses are also important because they can move reported earnings materially.
