Thanks all. I will try flying with pre-fitted adapters and try switching the headset over and test the performance, although that marginally reduces the usefulness of the handheld on the ground. It's true that loss of comms is not an emergency; I have simulated a 'no comms' approach and landing by prior arrangement with the tower. But given the busy environment I fly in, I would certainly cause disruption to ATC's sequencing and would presumably involve a lot of form filling after the event.
Ha! Just realized that makes the headset a single point of failure!
