How to Carry Earplugs for Concerts

I have become increasingly sensitive to certain sounds. It's very hard for me to concentrate or keep existing when that's happening. I've been starting to carry earplugs around for different events and different things. When you, when you put them in your ears, you're like, oh God, I can't hear as well. Also, people making, people making repetitive body noises, like sniffling. Oh, sure. That feels like a great merch opportunity for bands. Why are they not capitalizing on this?
