The above are child's play, I tell ya'...
I swear by these:
Highest db blocking available without a prescription. (If that's a thing, it just sounded clinical).
I keep the cute little United ones on hand as like a 4th-string backup in case my other three pair either fail me or go missing. Haven't had to result to them since the 'Connoisseur Class" version.
Signed,
A man who is an extremely light sleeper who has trouble falling asleep and has not spent a night without ear plugs in his ears in the last 20 years--at home, on an airplane, in a hotel, on a boat, etc. I simply cannot fall asleep without ear plugs. (I also have a white noise app on my iPad and phone, one of which plays next to me as I sleep).
