Or even easier is this: http://www.awdirect.com/hi-viz-radio-earmuffs-with-ipod-mp3-hook-up-1015543/safety-supplies/ Adopt-a-Redneck wears them whenever he's in equipment since none of it has radios. It gets annoying when you can NEVER get his attention though. Especially when you're trying to pull a truck out of the mud and you're yelling "STOP!!!!! STOP!!!!!" He's been using them since August and they must still work because he's always wearing them.
