My son is a full time firearms instructor and these are the muffs he uses. The ear cups are gel filled and replaceable. My hearing is not as good as it used to be so I wanted to be as possible when I shoot. Midway had a good price on them over Christmas.
I have used a pair of Sordin Supremes for several years until I switched to Peltors. The Sordins sound better, but I had several failures of the battery box. They got repaired under warrantee but it was a pain to be without them so I switched. Still use them for hunting and range use. I don't know if the battery box issue has been corrected with the new ones.
