The covers help to remove the pops and crackles from the mic, as well as fan noise and any (creepy) breathing sounds

These JUST fit over the mic and really help smooth out the sound.

VERY happy with these, so happy I ordered two pckgs, they make a HUGE difference in sound quality while teaching and no breathing sounds audible even during vigorous exercise, they fit the small over the ear mic piece very well

to crystal clear sound, instantly!

Works good to block wind sounds from fan etc

If you use a headset without one of these windscreens on it, these will do a great job and make everything much cleaner sounding.

It's a bargain for what it does - cutting wind sound into the mic (see my use).
