Hmmmmmmm. Good point there. I personally don't use hearing protection but then again I am not old and deaf. (insert cynical grin here) Honestly I do practice good safety including always making certain that I am in the RIGHT STATE OF MIND (No, Jose is not allowed on my tractor) when working. I wear my steel-toe engineer boots (after all I am an Engineer), long pants, eye protection & gloves when working near chemicals, cutting equipment etc. I also wear a full shield, including helmet and ear protection when using the chainsaw.
I personally would not want the distraction of anything else while I am out on the tractor. It is enough for me to listen to the tractor, be aware of any obvious debris, and potential hidden dangers, plus being able to be "alerted by people on the ground in emergencies" --- I agree with sixchows, I cannot imagine being distracted by music, talkshow rhetoric, ballgames or anything that is simply not of the essence to what I am focused on to accomplish. (especially when I have a deadly bushhog spinning a few feet behind my head)
YMMV
I am not a SAFETY FREAK but I do practice more than most out there and I think it does make a difference. Remember the addage: "If it is feels unsafe, it probably is. " ---- Leave the games where they belong on TV/RADIO and let the overpaid boys have fun on their own time, not during my fun time. Never understood that level of attraction to professional sports in the first place. I guess that is what makes the world go round.

Last thing I want to hear while enjoying my quiet peaceful time on the tractor is some commercials about Bengay.
