I've been using Eargasm earplugs for a number of years now; the translucent variety. I have a regular set and a backup set. I wear them in public and they've been a "game changer" in my life by offering much needed sound protection due to sound sensitivity I have related to autism. I purchased the High dB filters to outfit a pair that I can use exclusively for outdoor walks to provide better protection from loud vehicles and road noises. The High dB filter inserts provide noticeably more protection. I'm glad I purchased them. They're easy to swap out/insert. I still use my other pair that has the standard inserts when I need to hear certain things but want protection from unexpected and sudden loud sounds.
These work like the normal filters, but they make things a little quieter. If you want to hear things crystal clear, stick with the normal filters because the High dB filters can make some things, like conversations, hard to hear. If you want more protection, like walking down a busy street or working in a louder environment, these are great.
These plugs work great, blocking the loud noises and still able to have a conversation.
