Anyone seen the $30 specials at Wal-Mart? Other than the poor fitting looking ear pieces, they look like they just might work. They have some amplification, while I'm sure the frequency range isn't great, they have limiting circuitry that cuts sound at 85dB. For $30, they might be worth a try. If they work, they would be the ticket for hunting... Hell, sometimes I get my ears ringing with the call...
