I have tried several different products but none of the high end electronics even though I've wasted enough on every lower level product to buy a set. Muffs are not comfortable for me as I shoot F-T/R and they interfere with a comfortable cheek weld and are too ht in the summer so I've mostly used ear plugs vs muffs.
I have the Walker's and I don't much care for them. I have regular size ears but small ear canals and even the smallest ear foams are too big. Google it. It's apparently a fairly common issue with them. Also, even if they are off they will kill the batteries so you have to take them out every time. Also a common issue with them. Bottom line for me anyway is they are uncomfortable, the foams tear easily and the batteries are constantly dead.
I recently got a set of Decibullz moldable percussion filter earpieces and I love them. You boil water and put the bases in for 5 minutes and then form them to your ears kind of like a mouthpiece. They have an assortment of foams and silicone inserts so no issue with fitting any size ear canal. The percussion filter is a very interesting little device. It is passive so no batteries to deal with but allows normal sounds, conversations etc.. to be heard but suppress loud sounds. They work very well. Since you custom mold them to your ears they are very comfortable. I've literally had them in for several hours at a time and experienced no discomfort at all. I'm quite pleased with them. They are $75 and include 2 sets of bases along with the assortment of inserts and a nice case. They make similar ear pieces that do not have the filters that are only about $25. They are available on Amazon but I bought mine directly from the manufacturer so I could get some extra foams, lanyard etc... Worth a look in my opinion.
