wow, such controversy. here's my $0.02.

when I'm on the road alone or with a group no headphones for me. I'm slightly hard of hearing so I need every sound I can get plus...I wear a headet all day and once off work sick of the &^% things.

If you ride with me be forwarned I will sing for no apparent reason, just whatever comes to mind especially when climbing.

If I'm out in the boondocks I want to hear the birds, wind, creek etc. Don't do much off road riding but if I can hear nature I prefer that to any music, best soundtrack on earth.
