Does anyone out there have any knowledge or experience with this set up? Christmas brought me a new Nolan N-102 helmet and a N-Com basic kit 2 with a "X" multimedia wire (stereo type). I put the headset and speakers into the helmet (easily done); however, when the wire is plugged into a device, MP3 or GPS and music is playing I can only hear the music and not the lead vocals....WTF? If I back the plug out of the MP3 or the GPS a little bit then it plays everything beautifully. Of course since the plug is not fully inserted into the device, just kind of hanging there, this is not an option. What kind of bizarre electronic happening is going on here? I even tried a different cord that did not come with the Nolan kit and it does the same thing. 75% inserted into the MP3 or GPS audio jack sounds perfect (in the helmet just like it should) push the cord into the MP3 or GPS 100% and I either lose the lead vocals or part of the music.
