Oh, and one more thing. The foam plugs need to be rolled up TIGHT (like after picking a booger
) then inserted into the ear canal QUICKLY before they start to expand. Or they don't do squat. And sometimes it helps to pull out the outer ear from behind your head with the opposite hand to straighten the ear canal to aid insertion. My apologies for being long winded with these posts, but it is a simple thing to prevent hearing loss. And if anyone has back issues, Motorcycle Consumer News did a column or two awhile back that had good info.
