Narrative:

During [a tour] flight; one of the customers got his right arm wrapped around the cable from his headset. [As] he tried to untangle himself while holding to his camera (that was properly strapped around his neck); the headset fell from his head and ended up breaking loose from the connector that connects to the main part of the headset and [was] dragged out of the aircraft (during a doors-off sightseeing operation).the customer brought the fact to my attention tapping on my shoulder and showing me the cable from the headset without the headset.I confirmed no injuries were suffered by any of the passengers and flew the route back to the airport I departed from.to avoid the same mistake I will brief the passengers to be more careful with the wires and maintain calm if it gets wrapped around them; especially during doors-off operations.
