I've been following this thread and getting responses from Switchmonkey on another tread about connecting a Bluetooth transmitter to the DIN plug output, to Bluetooth to a wireless helmet headset. I've used Bluetooth receivers in helmets and always seem to forget to charge them and I'm not excited with the idea of being tethered to the DIN plug. I ride by myself so I don't need to talk to passenger and I DON'T want to take calls on the phone. I only want to hear my "USB" music.

A week ago I upgraded the stock speakers to J&M Performance XT Fairing Speaker and can hear music better at 65+ MPH. In Texas we have 75 and 80 MPH limits and I'm heading out west next weekend. By Monday I'll know if they work for my ears or not.

If necessary, I think my next step would be to change my 11" Baggershield to the adjustable 11"-19" Baggershield. The extra height should cut the wind noise at 70+MPH.
