My and I went for our first ride together after installing headsets in our helmets. As I expected, she wanted the volume lower on both the intercom and the music. Her ears haven't been in all the noisey places that mine have been. I plan to intall a rear volume control so that I can set the volume level to where I can hear well and she can turn it down to what ever level suits her. The only two that I know of are the Honda unit and the one sold be Big Bike Parts. Is there an advantage to using one over the other. The Honda part is much more expensive, but if it works better, what's another sixty or seventy dollars on Goldwing.
