^^this shorted out with some water...I like the fancy electronic suppressor type....
Surefire EP-4 passive plugs. Worth their weight in gold (which isn't much at $14 per pair. I've used them in every situation (indoor with rifles, outdoors, etc.) and have yet to get the "foggy concert" problem from noises which are too loud after shooting. My ears never ring and they are comfortable for all day shooting. I've put them against expensive peltors and find they work just fine. I can hear normal conversation voices in between shots. Honestly my biggest complaint about the muffs is my ears and head get hot and sweaty after a long time shooting. Less comfort means less enjoyment.
If you plug them up they work like normal earplugs and have a limit. If you open them they will block out noise up to 80dB. They work great.
What are you using and why?
What would you buy other than what you have...if you only knew then what you know now???
