I have been using Peltor Tac 6's for over 15 years. They run good, and are cheap now at about $60. Get the neck band style. If your budget allows, go for Sordin Supremes, about $300. http://www.sordinearmuffs.com/
You can hear shooters talking on the next stage..... The next step up is about $2,000. Digital in hear ear http://www.espamerica.com/p-14-esp-s...2-digital.aspx
I'll wait for the price to drop a little.
