You might experiment with a small piece of clear or colored adhesive tape across the top of the wind screen. The breathing noise comming from your nose is then kept from blowing across the mic. FB.
Hi, I bought a CM 311a used. It's about 4 years old. What I am wondering is have there any improvements to the new models that are not in the older models? Any reason to upgrade? I saw a picture on one website that looks like the wire frame over the ears is much thinner and smaller, but the picture on Crowns site looks like mine. Thanks fb
