This very problem is one of the major reasons I opted for a David Clark DC ONE X headset. I bought the Lemo connector model of that headset and two adapters, Lemo to UG174 and Lemo to GA plugs. I can run them in any aircraft, no fuss, no muss, and they will automatically switch to panel power when plugged into a Lemo panel connector. And, unlike the Bose, the DC ONE X has sufficient passive attenuation such that a battery or power failure does not constitute an emergency, only an annoyance.
