The Lectrosonics M150 is a professional electret condenser lavalier microphone engineered for broadcast, theater, film production, and live presentation applications where clear and natural voice reproduction is essential. Believed to be manufactured by Audio-Technica to Lectrosonics' specifications, this microphone is designed as a complete package for professional wireless systems.

Featuring an omnidirectional polar pattern, the M150 captures sound uniformly from all directions, which provides several practical benefits in production environments. This design minimizes handling noise and plosives while delivering consistent audio quality regardless of how much the talent moves their head during a performance or presentation . The omnidirectional pattern is also less susceptible to clothing rustle compared to directional alternatives.

The microphone is equipped with a TA5 connector that ensures seamless compatibility with Lectrosonics radio microphone transmitters, including the MM400 series and UM series systems . As a three-wire electret condenser design, it requires specific wiring configurations for optimal performance with Lectrosonics transmitters. The complete package comes housed in its original plastic case and includes a foam windscreen for reducing wind and breath noise, plus a durable microphone clip for secure attachment to talent clothing.
