Replacement cover for Fatality headset mic

you can move the mic from under your nose... or you can make a foam baffle from bath sponge. any soft material that isnt wrapped around the mic to tightly will work.
better still look for an old desk mic and take the mic sock off it and stick it on yours... i find a little double sided sticky tape will hold it firmly in place. just attach it to the back of the mice and slip the baffle over, then stick it down. its not gonna go anywhere then.
you could of course always email em and ask for a replacement... it will probably cost you £20 post and packing and 50p for the part...
you can go to your local music shop and buy a mic sock. they cost pennies to pounds depending on size...
