I use the Alpine [1], and I use them to protect my ears from the screaming of my toddler. They cost 13 EUR, custom-made cost around 150 EUR. Custom-made can be worth it if you use them a lot, and if your ears are non-standard might be downright mandatory.

But I've been using them too late because recently I have tinnitus in the evening before I go to sleep (I do wear the plug at night as well). Am in mid 30s.
