Late this summer I'll be going places where I'll be in places with near-deafening volume levels, but in which it would be very, very impolite to wear noticeable hearing protection. Yes, it's ridiculous. Welcome to Latin America! So I need to find some visually discreet earplugs. There are a lot of earplugs out there to choose from with a lot to be argued about, but trying to find some that are not obviously visible throws a new wrench into things. It's even harder to find what I need when I factor in the need to be able to have conversations with them in. I found earpeace.com and I'm considering those. 11 - 17 dB reduction, which isn't spectacular but I suppose is reasonable for what I'm after. Does anyone have any experience/knowledge that would be helpful here?
