Keep your headset mic clean! The CRAZEDpilot Mic Cover can be trimmed to fit almost every microphone out there including David Clark M7 and M4, Lightspeed, Bose, Telex, and everything else we tried. Once trimmed to length, carefully grab the headset mic muff cover on both sides and pull it down gently into place.
Will stay inplace on it's own. The o-ring is not necessary with our product - ours fit snugly and stay in place! The O-ring design is inferior from David Clark because if the o-ring splits, their mic cover falls off immediately. Not ours!
Headset mic covers for David Clark, Bose, Lightspeed, etc should be replaced annually for sanitary purposes, plus they help maintain the microphone quality - if the mic cover fails, moisture and dirt can then reach your microphone, which is an EXPENSIVE part. Order your CRAZEDpilot headset mic muff / cover today, and get a spare while you're at it!
