I can only speak for myself. I purchase EAR molded-in-ear plugs and carry them with me whenever hunting. Theses plugs are manufactured to fit your ear, in your ear. An EAR rep/trained salesperson places the moldable material in your ear, where is sets up to form a perfect fit. Like glass bedding a barreled action into a stock. The cost for a set of these is about $50. You'll have to research and locate an EAR dealer near you to purchase a set. They will last for years for purposes of hunting and shooting. Even under daily industrial use, they last for three or more years.
When practice shooting, I double up with a set of Peltor PS7 stereo ear protectors. They have electronic noise shut off when the gun is fired. In the absence of loud sounds, the muffs amplify lower decible noise/conversation. With these muffs on over my EAR molded-in-ear plugs, I can amplify the normal level sounds to talk in normal conversation, and when a gun is discharged, I have the hearing protection offered by both the EARs and the Peltors.
When hunting in the wilds of Alaska, I only carry the EAR plugs. They are much more effective than the $1.00 per set disposable foam ear plugs.
