The black Shure MX150B/C Subminiature Cardioid Lavalier Microphone is a tiny lav mic well suited for broadcast, sermons, presentations, public address, and much more. This version features a TA4F connection for use with Shure wireless bodypack transmitters.

The microphone’s diminutive size makes it visually discreet and allows for easy concealment. Shure’s CommShield technology makes the mic impervious to noise caused by mobile devices, WiFi, TV signals, and other RFI sources. This version of the mic features a cardioid polar pattern that focuses sound capture in front of the capsule for less background sound and reduced feedback, making it well suited to applications where sound-reinforcement equipment is used.

The MX150 includes a snap-fit windscreen and a multi-position tie clip with an integrated cable management system that minimizes noise without increasing cable strain and tension. A carrying case is also supplied.
