The Shure MX184 is a professional-grade, supercardioid wired lavalier condenser microphone designed for critical applications where superior gain before feedback and excellent noise rejection are paramount. Its supercardioid polar pattern is significantly more directional than a standard cardioid, providing enhanced rejection of sound coming from the sides and rear. This makes it an ideal choice for high-volume live sound reinforcement, theater productions, and broadcast environments where stage monitors or crowd noise could otherwise cause feedback or degrade audio clarity. Despite its miniature size, the MX184 is engineered to deliver a smooth, natural frequency response with a presence rise that ensures vocal intelligibility cuts through a mix without sounding harsh.

The microphone features a durable, all-metal grille and a robust strain relief at the cable entry point, built to withstand the physical demands of daily professional use. It is powered by standard 11-52V phantom power provided by a connected mixer, interface, or bodypack transmitter. The MX184 terminates in a 3-pin Tuchel connector, which is designed for a secure, locking connection to compatible Shure wireless beltpack transmitters or wired microphone inputs, ensuring a reliable link that won't disconnect accidentally. Its design prioritizes consistent performance and reliability, making it a trusted choice for touring sound engineers and broadcast audio technicians.

Typical applications for the MX184 include clipping to the clothing of vocalists, speakers, or actors in situations where a handheld microphone is not practical but maximum feedback rejection and ambient noise control are required. When used correctly with proper placement, it provides a clear, present vocal sound while minimizing the pickup of unwanted stage noise or PA system spill. It represents a high-performance tool in the audio professional's arsenal, offering the specific acoustic advantages of a supercardioid pattern in a discreet lavalier form factor.
