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 during 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. The WH20 is supplied with a foam windscreen and clothing clip.
WH20QTR has a right-angle 1/4 inch phone plug for use with Shure Headset Wireless Microphone Systems, or any unbalanced microphone input.
WH20TQG has a miniature four-pin female 4-pin mini connector for direct connection to Shure wireless body pack transmitters.
WH20XLR has a three-pin male XLR connector with a convenient detachable belt clip. Rugged, comfortable headsets that provides high-quality voice pickup for active mic users.
