This procedure is rarely necessary, but it may help if frequency response and 
directionality have deteriorated because the back ports on the element are 
contaminated with dust or makeup. 
Make sure your hands, the work area, the Earset’s boom and end cap are clean. 
Take a 6” - 8” piece of clean painter’s or gaffer’s tape and form it into a circle, 
sticky side out. Stick it down on the top of a table, near the edge. Do not use 
tapes that may leave adhesive on the mic.
Remove the cable and end cap. Hold the Earset by its boom, about an inch from 
the bare mic element. Lay the element down on the adhesive, with the earpiece 
hanging off the edge of the table. Gently roll the mic a full 360° along the adhesive 
to remove dust or debris. Replace the end cap and cable.
