Audio-technica ES915SC21 Cardioid Condenser Gooseneck Microphone with  Mute Switch/LED (21" long) The new Engineered Sound®. Contractor-exclusive innovations for every acoustical challenge. And safe haven from RFI. 
 Equipped with Audio-Technica’s legendary electro-acoustic design innovations, the ES915SC21 is a wide-range miniature condenser microphone, 21" long, with a cardioid polar pattern and a mute switch/LED. This small-diameter gooseneck microphone provides highly flexible positioning while maintaining a well-contoured appearance. The microphone offers unsurpassed immunity from radio frequency interference thanks to UniGuard® innovations. The ES915SC21 also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise. A mute switch in the base lights when the mic is “on.” The microphone’s low-profile element provides a uniform cardioid polar pattern with 120º acceptance angle. The microphone can be mounted on a podium or desktop with the included AT8474 low-profile isolation mount, which attenuates noise, shock and vibration transmitted through the mounting surface.
