Insta-Mold® Acoustic Filtered Earplugs are used to protect your hearing from sudden impact and constant sound levels such as wind nose, sporting event noise and even gunfire. The passive filter inside the plug allows any sounds under 85dB to enter but anything over that to be filtered out. This means that you can have your earplugs in AND have a conversation at the same time. No electronics, no batteries, no hassles. Custom molded to your ear.
Average Noise Reduction Rating (NRR) of 21dB.
The Insta-Mold® are a custom made product.
