The Shure MX183 is a professional omnidirectional lavalier condenser microphone designed for applications requiring a natural, open sound and consistent audio pickup regardless of microphone orientation. Its omnidirectional polar pattern captures sound equally from all directions, which is ideal for situations where the talent may turn their head or where a more ambient, less "proximity-effect" influenced sound is desired, such as in theatrical dialogue, panel discussions, or certain broadcast interviews. The microphone's extremely small and discreet capsule allows for easy concealment under clothing, while its rugged metal construction ensures durability for daily professional use.

The MX183 operates on standard 11-52V phantom power provided by a connected mixer, recorder, or wireless bodypack transmitter via its Tuchel locking connector. This secure connector prevents accidental disconnection, which is critical in live performance and broadcast environments. The microphone's frequency response is tailored for vocal clarity, providing a flat and natural reproduction of the human voice. Because it is omnidirectional, it is less susceptible to plosive pops than directional lavaliers, though it may pick up more room ambiance, requiring careful consideration of the acoustic environment.

Common applications include theater productions, where actors' head movements are frequent; conference rooms for tabletop or lapel use in boardroom settings; and any scenario where a neutral, non-directional pickup is preferred to capture the natural acoustics of the space along with the voice. The MX183 is often supplied with a variety of mounting accessories, such as lavalier clips and tie clips, to accommodate different clothing types. It represents a reliable, high-quality tool for audio professionals who need the specific acoustic benefits of an omnidirectional pattern in a discreet lavalier form factor.
