We're sorry to disappoint you, but that was nothing but an old-timey hearing aid -- which, obviously, one had to hold against their head, because the notion of making inventions tiny and convenient hadn't been invented yet. It's like when some weirdo thought a Civil War soldier pulled out an iPhone to give directions to the stagecoach driver in the 1948 western Fort Apache. That can't possibly be true. If that guy really had an iPhone, he would've insisted on recording the whole movie on it. Also, and we shouldn't have to be the ones to point this out, but unless these "time travelers" had some sort of slipstream technology installed in their OtterBoxes, there is no possible way their alleged cellphones would work in the past, because cell towers did not exist.
Truly, the incompetence of these highly advanced humans seems to know no bounds. Like when tabloids thought that some time-surfing hipster had dropped his vintage Swiss watch in the tomb of a Ming emperor?

Everyone in that crowd hates him as much as you would.
