Winston Score History

The full picture

Koss Corporation makes headphones and audio equipment for everyday consumers. The company is one of the oldest headphone brands in the United States, having invented the stereo headphone in 1958. Its products range from basic earbuds to higher-end over-ear headphones, sold mainly to individual consumers through retail stores and online channels.

Koss earns money by selling its headphones directly to retailers and consumers, primarily in the United States, though it has some international sales. The company is very small, with a market cap near zero and an operating loss, meaning it currently spends more than it earns. Koss has some brand recognition from its long history, but it faces intense competition from much larger companies like Sony, Bose, and Apple, which have far greater resources for product development and marketing. The main risk is whether Koss can find a way to grow revenue and cut costs before its losses become unsustainable.
