Honeywell AirSoft Corded Multiple-Use Earplugs feature a Noise Reduction Rating of 27. Honeywell AirSoft Corded Reusable Earplugs offer unparalleled hearing protection for shooting in a multiple-use earplug. These earplugs feature a unique, four-flange design that creates a better seal in the ear without that plugged up feeling you can get with other earplugs. This can be attributed to the noise-blocking fins, which form low-pressure air pockets in your ear canal. The result is more comfortable, more dependable earplugs. The firm stem and tapered design makes for easy insertion and removal. These earplugs also come with a high-visibility cord and convenient carrying case to help prevent loss or misplacement. This package contains two pairs and a carrying case.
