What are some good hearing protectors that you would recommend? We have use the Stihl (full ear covering) protectors but the foam padding seem to harden up within a few months and they become uncomfortable. I have tried some which have radios built in to the headset but they cost ~$45 each. Likewise the small ear plugs are a continual cost as you have to keep buying new ones (even though they are inexpensive). So my ? is what do you use and how comfortable do they feel over long periods of time. Thank You for your comments.
