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!

Expensive cord. But very high quality and the S/O can turn the volume down when i scream at her for giving me wrong directions. Worth every penny, so she claims!!

Tolles Kabel für den Sozia. Meine Frau kann sich die gewünschte Lautstärke selber einstellen. Würde ich jederzeit wieder kaufen.

I bought this cord with the volume control so that my wife could control her volume. I am hard hearing (according to her) and it works well. a little expensive, but worth the money if it keeps the wife happy. She's happy.

YOU HAVE TO MAKE SURE YOUR UPPER CORD WORKS WITH THIS CORD. I ORDER IT AND THEN HAD TO ORDER THE UPPER TO BE ABLE TO USE IT. MY WIFE LIKE IT THOUGH. I AM A LITTLE HARD OF HEARING IN ONE EAR,(PROBABLY BECAUSE OF HER NAGGING ALL THESE YEARS) AND LIKE TO TURN THE VOLUME UP WHILE SHE KEEPS HERS SOFTER.

Previous reviewer had a faulty cord. Transmitting on the CB works perfectly. This unit is extremely well made and has a solid volume pot unlike most aftermarket and Hondaline units. J&M really did this one up right. It's just the ticket for drivers like myself, for whom the stereo tends to be too loud when the passenger's volume is just right. My passenger gets more wind noise, and requires a louder volume. This lets me dial my volume down to comfortable levels. I'm impressed with the quality, feel, and usability on the road. I suggest mounting the little box onto the tunnel cover with sticky velcro, forming an S curve in the short part of the cord, just above where the cord connection is so the volume pot box doesn't drag and bounce against the shelter. Worked like a charm for me. The unit may seem pricey, but the quality is definitely there. A+++
