Thanks for the link Spectre. From the details that it gives, the Peltor Tact. 7 has the same, (or maybe just similar) feature as the ProEars. It seems as if my compact ones do too, to a degree. The ones that had to be replaced weren't as good as the new pair MidWay sent me. Since I bought mine, it looks like they added a new feature. A jack to add a CD player or radio.
Check out Spectre's link and call the company to ask them about the difference. Maybe they have the same electronics as the Pro Ears now...????
