Koss Headphones and Audio Equipment

Koss Corporation is an iconic American audio company that revolutionized the personal listening experience by inventing the world's first high-fidelity stereophone in 1958. Based in Milwaukee, Wisconsin, the company remains a pioneer in the headphone industry, known for its commitment to sound quality and its famous lifetime warranty on many products. While many professional and high-end models have historically seen assembly in the United States, current high-volume consumer production is primarily handled through manufacturing partners in China to ensure global competitiveness.

Ownership of the brand has remained remarkably stable compared to many of its competitors. Koss Corporation is a publicly traded company that is still largely managed and owned by the founding Koss family. This independence has allowed the brand to maintain its focus on audio fidelity and classic designs, such as the legendary Porta Pro, without shifting to a conglomerate-driven business model. Today, Koss continues to provide a wide range of audio solutions, from modern wireless Bluetooth headphones to high-end electrostatic systems.
