We can shop for top name brands of hearing protection devices in gun stores and sporting goods catalogs/websites, and we can pay premium prices.
Or we can shop for hearing protection devices made for industrial use (manufacturing, construction, etc), and quickly find that a number of outstanding products can be had for very reasonable prices.
I suspect that many of the top brand names marketing to the shooting public are nothing more than re-branded products, perhaps some cosmetic modifications and a logo added.
OSHA has standards that apply to industrial products for hearing protection. A brief period of research should identify what will meet your needs, then browsing through a few websites should allow you to make a good selection at a good price.
I discovered this years ago. I use a very inexpensive unit (less than $3 per in quantity) intended for manufacturing environments, which I buy by the dozen and share with family and friends at the range. Huge variety available, and lots of sources.
