I like Sordins, and lots of versions so check them out for your needs. Just electronic, BT to connect to your phone, etc.
Friends have Peltors, also totally happy.
Things like the Howard Leight work great until they do not. Not waterproof, so if you are going to be in the rain, even its just very humid and you sweat, they can fail. Some electronics turn OFF when there's a loud noise. Do not get those. Annoying.
All electronics have a volume control. With foam plugs in, you just turn it up 1 or two more notches. I think the audio is so clear on mine that it's easier to hear with them on than with just the foam plugs in.
Agree fully on gel ear seals. Never seen them leak; it's my understanding the gel is not a true liquid even when cut into it. They do wear out also, so I replaced some after about 10 years of use. Also good to get better foam for top bands. Unlike the gel seals, not offered by the mfg, so you have to find aftermarket, but worth it.
Foam ear plugs are mostly worn wrong, so check the how-to-install instructions. Here's some:

I got this info from factory work also, had to sit and be instructed in earpro install. I also brought my Sordins for better hearing and they also said I need to wear earplugs but I just palmed them as it wasn't that loud a place
Also for very loud things: sound doesn't only go in your ears. Your whole head is the receiver, and the Army for example specs their earpro, eyepro, and helmets to go together; they have an approved eyewear list that is not just ballistically rated, but also integrates with the other systems to provide overall sound reduction. Even just a hat and bigger eyepro can help if shooting very blasty stuff.
Watch for gaps. Temples on earpro will cause a small leak and discomfort so you'll take off the earpro more often. I use Wiley X SG1s and have the strap kit so they wear like goggles. Look into that also.
