I use the Howard Leight Impact Sport electronics and Leight Max foam plugs. I really like the Impacts, but I find that when shooting prone the stock-side muff gets pushed out of position and greatly reduces the effectiveness. With a NRR of 33, and $.10/pr when you buy the bulk pack, the Max plugs are great but it is much harder to hear range commands. I need to try doubling up the two and turning up the volume on the electronics to see about hearing talking.
Pretty close to what I have.
I may not be as high speed, low drag, as everyone here. But I was a competitive shooter for a few years. And probably fired about 30,000 + or - rounds a year. Usually with people shooting next to me. And my ears don't ring (I shot .22 when younger with nothing and I seriously regret it now). Mind you, this was outdoors. I make no claims about shooting next to someone using a muzzle brake next to a wall next to you on an indoor range. Ouch.
By all means DOUBLE UP. Plugs in the canal and muffs over.
I once tried the silicone molded plugs you see at gun shows. I do not recommend them personally, though some people seem to be happy. First, I don't think they attenuate the sound as well as the MAX plugs I link to below. Second, when I would make a good cheek weld they would often lose their seal a little bit. It may have been because my canals are big, wet with wax on a hot day, or whatever. I don't care. Not worth the risk. A few times in competition this happened and I didn't do anything about it and kept shooting and I regret that too.
As you work up to figuring out just how much you want to spend and what your needs and wants are, buy this right now. Don't even think about it (well, maybe, do read on).

If you have small ear canals (or female or child), get these (I also use these when needed while sleeping (they are more comfortable than the ones above):

These are not low-profile, however.

With the first and last links here you're out just a tad over $50. It's quite unlikely that you'll get a better bang for your buck in the shooting sports. In the future, you may decide to spring for better electronics. In the meantime, these will get you started.
And welcome.
