WH20 Dynamic Headset MicrophonesThe Shure WH20 is a rugged,
lightweight, dynamic headset microphone that provides high-quality
voice pickup. It fits securely for active microphone users, such as
aerobics instructors and musicians, with low visibility for stage
appearances. Suitable for any voice communications application where
comfort and reliability are required. The WH20 has a cardioid
(unidirectional) pickup pattern. This provides greater gain-before-
feedback and isolation from ambient noise and other unwanted sound
sources, such as air-conditioning, musical instruments and
loudspeakers. A carefully shaped frequency response includes a voice-
frequency presence peak and a low-frequency rolloff to compensate for
the proximity effect inherent in cardioid microphones d

uring close-talk operation. An integrated elastic headband secures the
headset comfortably. The headband, wireframe, and gooseneck are
adjustable to accommodate any head size or shape. WH20 is supplied
with foam windscreen and clothing clip. WH20QTR - Includes a right-
angle 1/4 inch phone plug for use with Shure Headset Wireless
