I got a pair of Etymotic’s ER20 ear plugs after seeing a few recommendations here on HN. I’ve worn them at concerts, at loud events, in a hotel next to the freeway, and even in the car when the driver had the radio too loud for me. Highly recommend them. I have small ear canals and the foam earplugs never worked, but Etymotic’s “standard” fits me fine, and also works for another friend with normal ears.
