For years this condenser microphone has been one of the top choices in the industry for lavalier microphones and can be found installed in many of the top wireless lavalier systems as well. It also can serve as an acoustic guitar mic mounted in the sound hole. The cardioid pickup pattern ensures the best possible pickup directly in front of the microphone while minimizing external noise, thus resulting in minimal feedback. The microphone comes with a tie/collar clip and terminates to a power module with battery. In place of the battery, the microphone can also be powered by +48v phantom power.


  • Clip-on lavalier mic also excels in acoustic guitar applications  
  • Provides crisp, full-sounding voice and instrument pickup  
  • Operates on battery or phantom power  
  • 6' (1.8 m) cable permanently attached between microphone and power module
  • Includes windscreen, clothing clip, instrument adapter, power supply, battery, and bag
