After significant research (on reddit and amazon and other places), I decided on 3M Peltor earbuds.
I cannot shoot a rifle with ear muffs because they prevent a proper cheek weld for me and the muffs get moved while I'm shooting and expose my hearing. Also, my hope was earbuds would better mimic natural directional hearing abilities since they seem more on the sides of the head. I was afraid with muffs I wouldn't be able to tell if a noise was to the left or right.
All other ear bud brands had too many bad reviews. I decided I was not interested in ones that also had bluetooth function so you could take calls or listen to music. It seemed that those features were the ones that way too many people said would break. Also, it adds complexity and is not needed by me when hunting.
The 3M Peltor ear buds come in at least 2 flavors. The neon green ones are for industrial settings and is what I got. The black ones are tactical and are for shooting ranges and such. When I researched if the green ones would work for hunting, I found out that they would when only there is occasional loud noise. At a shooting range, the earbuds have to "work" all the time as shots are fired and it supposedly stresses out their batteries. The black/tactical ones are made to withstand that.
I just wear regular foam plugs at the shooting range and only wanted these for hunting. So, I bought the green pair which is cheaper (I went to 3Ms site and found them for like $200). There are wind muffle accessories and several different size and types of tips that go on the end and in your ear. I liked the brown latex ridged ones the best and ordered like 30 of them as spares. I bought but did not need the wind muffs because when rifle hunting this year I found that either the wind wasn't blowing or if it was then it was cold enough to have my ear flaps down and that stopped wind noise (the wind muff thing is like a little foam end on a microphone).
I tried these first with a 22 LR and then my deer rifle and hunted with them all year.
So, far, they are slicker than cat crap and I cannot be happier with my purchase. There are 3 volume settings and the highest volume is maybe 25% louder (when not silenced during a shot) than normal hearing.
