Here is what did. ligthspeeds with lemo plugs - cable tied the controllers up the top just forward of head so i can see to adjust if needed. you can see there is sufficient chord to run it backwards and then down with the fuel lines so there is no chord in front of me. I store the headsets in the little pockets in the luggage container. I hated having all the chords around my knees in other planes! And wiring with a lemo plug means I need no batteries for the noise cancelling.
cheers
