If you want as much noise reduction as possible in a standard, non-electronic earmuff, these howard leight L3s may be perfect. I think they are ideal for indoor pistol shooting, but for outdoor rifle shooting there are better options out there. These stick out a lot, they're very thick, so it's guaranteed they'll prevent you from getting your face onto your rifle's stock. I prefer gel plugs for rifle shooting, though I may try the Howard Leight slimlines. Theres nothing wrong with these otherwise, they're just bulky, but perfectly comfortable. I intend to keep them as a loaner-pair for friends or family members to use.
Pros: comfortable, durable, inexpensive
Cons: have to be constantly be adjusted, very bulky
