I like the construction comparison. Go to any equipment dealer and see how many units come standard with a radio. Also I can't translate the difference between hearing protection vs. the same protection producing musc? They still muffle the same decible level so that rules out the inability to hear background noise. I wear earbuds and I can hear just as much, and am just as attentive as if I were wearing just earplugs. Also the insurance company is going to find something wrong to dispute your claim no matter how you run things.
