I've got flange-shaped earplugs for the motorcycle, they seem to be just fine. Pulling up the ear is good practice for any kind of earplug though, I presume it straightens out the ear canal or something like that, I've used it for audio earbuds as well for a long time.

If they fall out, get different ones.

My dad had custom molded ones for his job (in metalwork), but that was well after the damage was done. He had tinnitus and he's now finally budged and got himself some subtle hearing aids.

You can do the custom-molded ones yourself now, I had some for motorcycle riding and they worked very well. Unfortunately the ambulance cut them off of me when I got in a wreck so they are toast now, but they did their job great up until then!

I used https://earfuze.com/ but I'm sure there are better ones out now.
