Both "boomset" and "headset" are terms used e.g. by Airbus:
The audio management system includes:
- [...] sockets at each station
- headset jack and boomset connector (hand microphone connector) for pilot, copilot and third occupant
- headset jack for fourth occupant
- [...] boomsets for the pilot, copilot, and third occupant, and three hand microphones (fourth) [...]
What's the main difference between these two things or are they the same?
