I liked the day where everyone just decided to post all their voids and just kinda took over the feed.

That was a really nice day :)

I’ve tried the foam earplugs from a drugstore/chemist’s. They’re extremely difficult to put in properly

Take the earplug and roll it between your fingers until it’s a smaller size that goes in easily. Take your other hand and grab your earlobe toward the back and bottom. Pull your lobe backward and away from your head; that straightens and opens your ear canal. The combination of these two should make it easy to insert the earplugs.

[If you like, you can play around with putting the tip of your finger at the entrance of your ear canal and then pulling the lobe with your other hand, to feel how it changes the entrance to your ear canal.]

and get dirty after a few uses.

Maybe clean your ears? Also, most of the cheap foam earplugs aren’t meant to be a long-term solution, they’re definitionally disposable.
