Shure 55SH
The Shure 55SH is a professional cardioid dynamic microphone that has been commonly used in broadcast applications since 1939. Designed by Shure, it has been described as an industry standard microphone, "iconic" for its perfect sound and wide adoption in radio, television, and recording studios. From the 1940s until the end of the 20th century, it maintained its popularity in the professional environment. Shure designed the Unidyne transducer in 1939 and then greatly improved it in 1959, based on research and development by Shure engineer Ernie Seeler.
