Peltor Ultimate 10
I'll have to affirm the previous recommendations about the Peltor Ultimate 10.
They're $30, they provide 30NRR dB reduction rating, they're lightweight and comfortable. If you throw on some foam in-the-ear disposable plugs underneath them, you'll have your hearing for a long time. AFAIK, they have the highest NRR out there of all the current headsets.
Frankly, don't skimp on (1) hearing protection and (2) eye protection. You can't get either of them back once you lose them, and for $30, there's no excuse not to use the best.
I got mine at Bass Pro, but you can find them online for a little less.
