I am using the single Harley/J&M helmet headset for CB and bluetooth calls. There is a special (low cost) interface that allows you to plug into the 2.5mm jack on the Zumo bike mount (located above the Zumo audio out 3.5mm jack) and allows you to use your Harley/J&M helmet headset for both CB and bluetooth.
Simple, clean, invisible, inexpensive and crystal clear calls at 70mph!
I tried many many many bluetooth headsets and above 30mph wind noise made them useless.
Ok, here's the skinny. The Z has a 2.5mm jack above the audio-out for a micrphone.
In my case I ran the wire from the 2.5mm Z mike-out inside the handlebars and under the center tank dash.
Again, in my case all my wires are inside the bars. I also ran the audio-out from the Z in the bars and added an additional AUX to the back of the HD radio. Hence, the extra work (In my case) to put the wires inside the bars.

I can remove the Z's bike mount with the audio-out and mike-out in less than 5 seconds in order to lock it up.
Depending on your setup if you have wires under your bars you could follow them.
In the tank dash, where you plug in your helmet headset, there is a wire with a round pin connector at one end (where you plug in your headset) and the other end of this wire is a Deutsch connector that plugs into the wiring harness.
Unscrew the tank dash then unplug the Deutsch connector from the wiring harness and plug in the interface between the connectors.
One end of the interface plugs into the headset dash wire Deutsch connector end and the other end plugs into the wiring harness Deutsch connector. Basically, the interface plugs inline between the two Deutsch connectors.
Headset dash cable/Deutsch end <> Interface <> HD wiring harness. Male to female connection.
The mike jack wire (from the Z) plugs into the interface and now the headset will do cell calls and CB w/the single helmet headset.
The interface is small and hides under the seat.
It sounds complicated, however, if you are running the mike-out wire from the Z under the bars. Pulling the tank dash cover, unplugging the Deutsch connector plugging in the interface, plugging in the Z's mike out wire into the interface and buttoning up the tank dash takes about ten minutes to install.
Install time = less than one beer.
Wanna check it out on the cheap?
Go to Radio Shack get a 2.5mm lapel mike ($5-$10) plug it in the Z and make a call.
Don't wanna have a extra wire from the Z to your helmet with an alligator clip attaching the lapel mike to your helmet mike...(it does look funky) then the interface works great and you're using your helmet mike.
Your cell phone is on your belt and your helmet is on your head.
