I got the first chance to try these at Austin City Limits festival and one of them went bad right away. I put them in my ears per the instructions but one of the earplugs sounds like a blown speaker, for lack of a better example. This may just be a problem with these kinds of earplugs because they use a small disk - like a speaker cone - to dampen the sound without distortion. I guess that just means it can be blown out like a speaker. Bit saddened since these cost 15x what a pair of foam earplugs do.
