The Shure MX150B/C-TQG is a professional lavalier microphone designed for discreet and reliable voice capture in broadcast, presentation, and theatrical applications. This omnidirectional condenser microphone features an extremely small, low-profile capsule that can be easily hidden under clothing, making it ideal for situations where a visible microphone would be distracting. The "B/C" designation typically refers to the connector type (such as a TA4F mini connector for use with Shure bodypack transmitters), while "TQG" often indicates a specific package including tie clip, windscreen, and other mounting accessories. The microphone is engineered to deliver a natural vocal tone with a presence boost for enhanced intelligibility, ensuring clear and articulate speech reproduction even when the mic is placed under fabric.

A key feature of the MX150 series is its rugged construction and consistent performance. It requires bias power (typically 5-10V) supplied by a compatible Shure wireless bodypack transmitter or a plug-in power supply. The included cable is thin, flexible, and designed to minimize handling noise. The microphone's omnidirectional pickup pattern captures sound evenly from all directions, which is beneficial when the talent moves their head, though it also means it will pick up more ambient room sound compared to a directional mic. To combat plosives and wind noise, it comes with a effective windscreen. Various mounting clips and ties allow for secure placement on lapels, ties, or other clothing.

The Shure MX150B/C-TQG is a trusted tool for broadcast journalists, public speakers, and performers who require a discreet, high-quality audio solution. Its combination of small size, durability, and clear sound reproduction makes it a staple in professional audio kits for film, television, and live events. By providing reliable, hands-free audio capture from an almost invisible package, this microphone helps ensure that the focus remains squarely on the speaker's content.
