That's what I'm going to do now that I got my fitted ones. Impact sports with disposable plugs works well for boomers in enclosed shooting areas.
I figured I would update. I got a pair from Costco with a vent so you can hear people speak. I tried them out at the range, and well they SUCK by themselves. I think I may need to use costco's 90 day return policy and get a pair without a vent. I mean I may as well been wearing nothing, when just wearing them around the benches. Doubled up they are OK, not good as my reusable ear plugs from howard leight with a cost of 2.99$.
