I just use regular old foam earplugs. I keep a couple in my back pocket so that I can pull them out whenever needed, which is very often in urban environments and surprisingly often in suburbia. Also I can lose them constantly and it doesn't matter because I have a big container with more. Occasionally some random person asks me a question and I have to pull one out and say "what?", which is a bit awkward, but thanks to my hearing loss I would have had to say "what?" anyway - when someone talks to me and I'm not "ready" for it it sounds like an adult talking in a Peanuts cartoon.
