I’ve used all three over the years and each has its place depending on the situation. Foam is cheap and effective, muffs are easy and electronic makes communication a lot nicer. What do you prefer for hearing protection and when do you switch it up?
When I go to the range myself, I grab foam earplugs. But I use electronic ones when I'm with friends or in classes. Earmuffs come out when it's cold. I switch depending on what's comfortable and what the situation is.
Decibulz! I swear by them. Custom, moldable and comfortable. The ones I use are percussive. You are able to have normal conversation and they close with close with the loud noise. There are a handful of us using them and everyone likes them. Best part is you can wear them for long periods of time without discomfort.
I shoot a lot, but have the benefit of a private range. Still however, I generally double-up with both foam and muffs. (My ear muffs are electronic too, but in my situation, where I’m generally shooting alone, I seldom turn them “on”. Shooting suppressed really helps too, but even with the suppressor attached I still double-up.
