Fun Facts About Koss Corporation

• Koss began in 1953 as a hospital television rental company in Milwaukee, before switching focus to audio and headphones a few years later.
• In 1958, John C. Koss and engineer Martin Lange Jr. introduced the SP/3, widely regarded as the world’s first consumer high-fidelity stereo headphone, effectively creating the modern “personal listening” category.
• The original SP/3 headphone was developed only as a demonstration accessory for a portable phonograph at a hi-fi show, but audience reaction was so strong that the company pivoted to headphones as its core business.
• Despite its worldwide brand recognition, Koss employed only about 31 people as of 2023, making it a very small public company by global electronics industry standards.
• The Koss family controls roughly 74–75% of the company’s outstanding shares, and the business is still run as a closely held family enterprise.
• John C. Koss started the business with only about USD 200 in initial capital and built it into a global headphone brand without any formal education beyond high school.

• Beyond headphones, the company created the Koss Classics label, which released orchestral recordings, including projects with the Milwaukee Symphony Orchestra and other ensembles, positioning Koss as a niche classical music publisher as well as a hardware maker.

• To manage costs and supply chains, Koss shifted a significant share of its manufacturing from China to Mexico around 2014, while continuing to design products in the United States.
