Shure’s history of innovation can be traced back to the 1920s when S.N. Shure began selling AM radio kits and components from a small storefront in downtown Chicago. Shure’s passion for creating the finest microphones and audio electronics continues to set the industry standard for superior, reliable products. With the introduction of the Model 33N Two-Button Carbon Microphone, the 1930s saw the company expand greatly and become one of only a few U.S. microphone manufacturers. The Model 33N was a lightweight, reasonably priced microphone in contrast to the industry standards which were much heavier and much more costly. The Model 42 was Shure’s first condenser microphone and the Model 99 Modulator was Shure’s first wireless microphone. The Model 55 Unidyne Microphone was the world’s first single-element unidirectional dynamic microphone.
War dominated the 1940s and Shure became an important supplier of microphones and headphones to the Allied Forces. The T-17B Microphone became the most popular microphone utilized by the U.S. Army and Navy. The T-30V Throat Microphone, HS-33 and HS-38 Headphones, M-C1 Microphone for oxygen masks, Model 100 Carbon Microphone, and Battle Announce Microphone were also manufactured for the military during this period.
