Thought I would give one of these a try and it sure looks like it works better than expected .  A leather mic muff you can get off e-bay for $9.99  , free shipping and no tax .  About $5.00 more from Spruce and Oregon Aero .  It blocks about 90%+ of background noise and my transmissions have never been clearer .   

   You can also make your own with an old leather glove by just cutting off one of the fingers and making the 2 small holes that are required to make it work .  They come from TinasPilotShop.com , but for some reason they are not listed on her web site ?  I use the budget headsets so not sure if they work on the $500 headsets you all big spenders use .  I suppose you can call Tina and find out .  1-817-490-0046 .
