Thanks for the info. I've checked the web site, and of course, have a question. Which one do you recommend for a concert? My issue is I've been to 70+ Stones shows, too many Black Crowes shows, and 200 other shows and have tinnitus. I don't want (nor my wife) my ailment get worse; I've been to many shows following the issue but with crappy plugs that I just take out
Thanks.
