Bose Headeset - Airplane+Helicopter

I am considering getting one of the Bose headsets. I fly both
airplanes and helicotpers and am wondering what the best solution is.
On the Bose website under accesories for the headset they list a
helicopter cable for $195. Does it make sense to buy the airplane
headset plus this cable and swap the cable when I change aircraft, or
is swapping cables too big of a fuss to deal with on a regular basis?
Is there a difference in the electronics of the airplane versus
helicopter cable? Am I better off just getting a cheap generic adapter
and dealing with the excessively long cord in the helicopter? Or,
perhaps its better to get the helicopter model and get an adapter to
use in airplanes. Does anyone have any experience using their Bose in
both airplanes and helicopters? It does seem extravegant to shell out
an extra $195 for the helicopter cable.
