Wow. I guess I'm in the minority here. Here being APC. I wipe it down first. Does that count? And no, I'm not a germophobe. But I'll GUARANTEE the ship headset was plugged in before you - or the previous other Bose headset user - unplugged it in the first place.
I won't dog you for using your own headset. But if you unplug the ship set, you should plug it back in after you're finished. If not, then I disagree.
I've seen the frustration MANY times from my fellow crewmembers when dealing with this. While it may be trite to be sure, and I can't speak for them, I'm willing to bet you may not see the "lost and found email" should you ever forget your $500 headset.
