Got stuck in my ear canal.
They worked ok for quieting sounds while riding my motorcycle. I've used better, though. My main issue was that one somehow wiggled so far into my ear canal that I couldn't get it out with my fingers. The post at the end wasn't long enough to do so. Luckily I had a friend and some needle nose pliers close by. Into the trash these things went.<br /><br />By the way, I've used lots of similar products and that has never happened with any of them. I don't have abnormally large ear canals.
