GENERAL

The Shure Model WH10 is a dynamic headset microphone intended for use in applications where light weight, maximum mobility, and high-quality voice pickup are absolute

necessities. These include such

auctioneers, aerobics instructors, and

diverse applications as

square dance callers. Additionally, the WH10 is an optimum choice for automatic speech recognition, voice communications, and voice annotation

applications

where hands-free operation is desired. The WH10 has a cardioid unidirectional pickup pattern that provides isolation from ambient noise and from adjacent sound sources such as machinery, air-moving equipment, musical ity sure

instruments, loudspeakers and other talkers. Its clar

in close-talk operation combined with a high sound pres

level capability make the WH10 an

excellent choice for

all mobile voice situations.
