The AT899 is designed to be worn as a lavalier or hidden in loose clothing or in the hair. For use as a lavalier, attach the microphone about six inches below the chin. Anticipate movements that may cause the microphone to rub against or be covered by clothing, and position the microphone to avoid it.
The included single and double mic holders are interchangeable with all the bases. To change the holders, simply remove original holder and snap in the desired one.
