Like the Mini Headset, the Off Shot active devices offer three sizes of foam ear plugs to ensure proper fit in any size ear. I found them to be very comfortable and easy to put in. The plugs offer a base protection of 32 decibels (if they are simply inserted in the ears and turned off, they will block all noises by 32 decibels). When the plugs are on, the technology provides sound amplification so you can hear sounds under 85 decibels clearly. If a noise, like a gunshot, is over 85 decibels, the digital plugs reduce it by 32 decibels—all in a package that weighs just 7 grams.
