General Description

The Shure SM10A is a low-impedance, unidirectional dynamic microphone designed for close-talk headworn applications such as remote-site sports broadcasting and corporate intercom systems. It is also ideal for singing drummers, keyboard artists, and other performers who need a headworn vocal microphone with superior noise rejection and a smooth, naturalsounding frequency response.

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° in any direction. The boom also slides out so the microphone can be positioned up to 89 mm (3 ½ in.) from the pivot housing. A supplied windscreen reduces wind noise and explosive breath sounds. A belt clip that fits over the XLR connector and attaches to the user’s belt or waistband provides cable strain relief.


  • Unidirectional cardioid pick-up pattern for excellent rejection of unwanted sound
  • Tailored frequency response specifically shaped for speech
  • Designed for close talk operation; ideal for use in noisy environments
  • Light weight headband minimizes user fatigue and does not interfere with eyeglasses
  • A clip fits over the XLR connector and attaches to the users belt or waistband, providing cable strain relief
  • Adjustable microphone boom with locking pivot can be moved 20 degrees in any direction and extends to 89mm (3 ½ in.)
  • Stainless steel aluminum and high-impact plastic construction resist wear and abuse
  • Shure quality, ruggedness and reliability

Mounting the SM10A on the Headband

  1. Twist the lower headband arms 90° so they are perpendicular to the headband. As supplied, the retaining clip is positioned for left side operation.

    Note: For right side usage, remove the retaining clip and attach it to the other (unused) hole in the headband arm so the screw is at the top.

  2. Snap the microphone pivot housing into the retaining clip with the pivot adjustment knob upward and the microphone toward the front.
  3. Loosen the pivot adjustment knob and position the boom so that the microphone is near the side of the user's mouth. Then tighten the pivot adjustment knob.
  4. Place the assembled microphone on the user's head and pull the headband arms downward until they are just above the ears.
  5. Loosen the pivot adjustment knob and position the microphone as close as possible to the corner of the user’s mouth. Then tighten the adjustment knob.

    Important: Position the gooseneck so that the microphone grille (silver side) is within 25 mm (1 inch) of the right corner of the mouth. Do NOT position it directly in front of the mouth. This will eliminate explosive breath sounds ("pop").

  6. Snap the belt clip over the groove in the XLR connector at the end of the microphone wire. Then attach the clip to the a belt or waistband.
  7. Plug the microphone XLR connector into a microphone cable or preamplifier.
