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 .
