The SHURE's MX150BC-TQG subminiature cardioid lavalier microphone is a compact lavalier mic perfectly suited for broadcast, sermons, presentations, and public speech. This condenser microphone is aesthetically unobtrusive and easy to conceal. Shure's CommShield technology prevents noise from mobile devices, WiFi, TV signals, and other RFI sources from entering the mic. This version of the mic has a cardioid polar pattern, which concentrates sound capture in front of the capsule for less background noise and less feedback, making it ideal for use with sound reinforcement equipment.
