The SM10A is very lightweight and is typically mounted on the supplied steel headband assembly. An adjustable pivot on the headband assembly allows the microphone boom to be moved 20 degrees in any direction. The boom also slides out so the microphone can be positioned up to 89 mm (3 1/2 in.) from the pivot housing. A supplied windscreen reduces wind noise and explosive breath sounds. Other features:
Close-talk design provides excellent isolation and minimizes gain-before-feedback
Extremely rugged with fully adjustable headband and microphone boom
Unidirectional(cardioid) polar pattern for superior rejection of unwanted sound
A clip that fits over the XLR connector and attaches to the user's belt or waistband, providing cable strain relief
