Agreed. This is a troll thread. Well... it began as a troll thread. Along the way, however, like most such threads, it picked up the assorted wisdom of numerous sincere posters who offer well meant but biased opinions. I have to say, I am saddened, but not surprised at the number, even in this small sampling of cyclists that think that using only one ear-bud is better than using two. Friends... its the distraction, not the reduction in hearing acuity! You will be just as distracted with Aerosmith pounding in one ear as two. Just because you haven't been killed yet is not an endorsement.

Hmmm. Given that this is a commuting forum and in these very pages we have heartfelt testimonials from cyclists that do not use mirrors, helmets, fenders, clipless pedals, gears or front headlights and there isn't much wonder why American cyclists have such poor metrics in the various categories measuring accident statistics and other indices of road safety and overall enjoyment of the cycling sub-culture. Rock on.
