I broke down and bought a 6-1 Nolan N43 Helmet a couple weeks ago, installed the stock Harley headset and like it a lot. Going to try the CB side next week on our ride to Daytona for bike week. Also from an earlier post Adjust your Speed volume lower, should solve any feedback issue!!

 

I have used the Harley headsets on my last three bikes and am more than satisfied. I have had J and M but they didn't hold up for me. i listen to music, CB and nav system. I just bought a new full face helmet. During my shopping I found that the Harley headset will not fit into all helmets. They will not fit in the new Shoei helmets, but fit perfectly in the Arai RX-Q.

 

I use Sena with full face helmets. Never tried anything else, but I like it. I bluetooth music from my phone through the speakers in the helmet. I can also answer and make phone calls using the headset while I'm on the road (yeah, yeah I know... no preaching about cell phones on the bike please!)
