well, I tell you one thing. When I start back up this spring I am going to be wearing some tunes. I tried it out last month while doing snow removal and everything moves so much faster I feel. Also I need to protect my hearing a little bit as well
I was going to buy the Shure E3 isolation headphones cheapest I found them was $112. Asked a friend about them, he said he could do it cheaper and he thinks they use the same lab as Shure. Noise reduction should be 30-35 dba.
