Worrying amount of people not wearing ear plugs to concerts, festivals…(r/Music)
Etymotic makes great pairs of earplugs exactly like that for less than $20. I have a pair and I can carry on a conversation while wearing them at a concert. They aren’t custom fitted like the expensive ones, but they are far better than the foam kinds.
