Shure MX150 Subminiature Lavalier Microphone

The MX150 is a professional subminiature electret condenser lavalier microphone ideal for use in speech and other applications requiring low-profile, discreet placement. Available with cardioid or omnidirectional patterns, the MX150 provides uncompromised sound quality and high reliability with minimal visibility for use in television broadcasting, corporate lectures, A/V teleconferencing, House of Worship, and sound reinforcement. CommShield®Technology offers superior RF immunity from cellular devices and digital bodypack transmitters. Each microphone is supplied with a snap-fit foam windscreen to minimize wind noise and a multi-position tie clip with integrated cable management to minimize cable handling noise.

• CommShield® technology helps reduce RF interference from wireless devices.
• Kevlar®-reinforced cable improves durability for daily professional use.
• Snap-fit acoustic caps allow quick replacement and maintenance.
• Includes multiple mounting options for clothing, ties, and lapels.
• Suitable for corporate AV, broadcast production, theater, houses of worship, education, and conference applications.
