Equate Ultimate Fit Foam Earplugs, 33 dB noise reduction rating, 50 Pairs

I use the one's from Walmart. I reuse them for about a week or so and replace as the foam starts to not spring back as well as new. My last bottle lasted about 14 months. https://www.walmart.com/ip/Equate-Ultimate-Fit-Earplugs-Foam-50-Pairs/5093611839?classType=REGULAR&from=/search
