If you're serious about your hearing I recommend these:
https://1of1custom.com - but, a set of the regular old ubiquitous orange foamies, inserted properly, is the next best thing.
AND, of course, muffs over those.
Worn over plugs, all the usual headsets/earmuffs: MSA/Sordin's/Peltor's/Impact Sports/etc are about the same and add an additional +5dB of noise reduction (assuming you maintain a good seal, ...gel cups always).
= 34-38dB NR
BTW/FWIW: much of the audio/amplification advantages the more expensive muffs have over the cheaper muffs disappear when worn over plugs: Sordin Supreme Pro-X's vs Impact Sports worn "naked" is huge, ...with plugs, not so much.
If you want Gucci of the Gucci you want the OpsCore AMP headset with near field magnetic induction (NFMI) earplugs. 34dB NR with 1:1 hear-through, bad-ass. NFMI plugs turn your ears into part of the speakers, very cool. But, even the $1000 AMP headset alone is still only 21dB NR, not enough protection without the plugs...
