Bought one of these for my wife thinking it was the way to go. In reality, you really need to buy 2 of these because it’s pointless only being able to turn the volume down from the pillion seat. For my wife to enjoy her music I need to turn the music up beyond the point that I’m willing to listen to it at. I do still want to hear what’s going on outside my helmet.
And for those thinking why don’t I swap the leads around – it’s because the master controls are on the handlebars – and leaving the pillion with no controls is not good.
The solution is 2 of these cords allowing independent volume control and set the volume high on the bike to start with….EASY…

Rode in gusty conditions yesterday. When we arrived home, we noticed the volume control knob on her headset cord was missing. Looks like a trip to Radio Shack to try to find a replacement.

I use this on the front because my wife likes music louder than I do. Now I set the audio volume to her taste and can turn mine down. Works great. Peace in the family again!

My Pasenger loves the Volume Control on this cord. She can set her volume independent of mine. I do not have to worry whether I have the volume to loud or not loud enough. Great Quality

I think this cord will outlast me! Thumbs up!
