These 3M 1100 earplus are magic. (You can get them at Screwfix in the UK.)

I always keep a few spare packets in my bag. On a few occasions (usually conferences) people have been grateful for them.

After a bit of research I found these https://www.happyearsearplugs.com/
These don’t go into the ear as far so aren’t painful. I feel the reduction in noise isn’t as good, but the frequency response is much more even. I wear these under noise cancelling headphones to watch TV and listen to music in total isolation. You do lose a bit of fidelity but it’s still very liveable.
Also, I get about 6 months to a year out of each pair which is less wasteful than foam earplugs.

I've never tried the 3M 1100s, though.
You can usually get a box of 200 pairs for ~£20 on Amazon.
