In 1944, the production line for the Shure Headset Department had grown from four people to more than 80. The assembly was complicated and exacting, requiring the women and men on the line to configure precisely the many specialized parts that made up the equipment. Each part of the headset cartridge was washed in a special machine. Complete cleanliness was assured by assembling the microphone cartridge in a dust-free, air-conditioned room. Shure was known for meeting the wartime demand for large quantities of headsets and other Shure products while maintaining consistently high-quality standards.
