Shure R183B Black Omnidirectional Cartridge for MX- (Microflex®) Models and WL183

The Shure R183B is a black omnidirectional replacement cartridge for Microflex series lavalier, boundary, gooseneck, and overhead microphones. The modular screw-on design lets a worn element be replaced, or the polar pattern changed, without purchasing a complete new microphone. It fits Microflex models including the MX183, MX202, MX391, MX392, MX393, MX412, and MX418, as well as the WL183 lavalier microphone.
