The Shure Model WL93 Microphone is an omnidirectional, subminiature, lavalier electret condenser microphone. Its visually unobtrusive design and tailored frequency response make them ideal for body-worn applications in TV broadcasting, theatre, and sound reinforcement. It features a small microphone element that provides full, clear sound comparable to that of much larger microphones. The WL93, intended for wireless use, connects directly to a Shure wireless body-pack transmitter.

The WL93 omnidirectional miniature lavalier condenser microphone is designed for use in speech applications such as broadcast presenting, speeches, lectures and for use in houses of worship.

The WL93 is supplied with a sew-on mounting bracket, a mounting block with attached tie bar, and an acoustic windscreen to minimize wind noise in outdoor applications. It is also supplied with a dual mounting block with attached tie bar.
