Founded by John C. Koss in 1953, originally as a hospital TV rental business, they are based in Milwaukee, Wisconsin, USA; in 1991, Koss Audio & Video Electronics started producing and selling consumer electronics products as a separate company in Hazelwood, Missouri, USA.

In addition to selling headphones under their own brand, Koss headphones are also rebranded as Radio Shack headphones under license and sold in Radio Shack stores. They will usually have the same drivers as the Koss phones, and these can usually be spotted by the fact that the minijack connector has the Koss logo on it. Radio Shack sells them as Titanium Diaphragm headphones. Some of their more popular products are the Koss Plug and Koss Spark Plug which are noise isolation earphones. Their ability to be adapted to take the high-end Etymotic ear tip (known as the Koss Hybrid), and the popular Koss Porta Pro has contributed to their success. Their budget-priced headphones (the KSC series in particular) are widely regarded as some of the best low-end headphones on the market.
