I use Honeywell Laser Lite earplugs for everyday noise reduction (autistic sensory sensitivity) and I chose them because they are the go-to for construction comrades, who gave me my first sets to try out. You can buy a large box online. They can be reused several times. I keep them in a pill bottle between uses to keep them clean, and I throw them out when they start to lose their ability to expand well enough to seal in the ear canal.

I tried silicone earplugs but they were too firm and caused irritation, and constantly lost their seal when I moved.
