I vote for a passive audio receiver. The spiral pattern reminds me of an inductive RFID tag, so best guess is that someone wants to pump out enough radio energy into the "aether" that it can power a set of headphones and deliver info appropriate to the "space" you're walking through.

For bonus points, I wonder if the choker is intended to work in the other direction as well... the movements of the throat would alter the resonant frequency of the receiver enough that the transmitter can pick up (some indication of) the wearer's speech.

the mystery photo looks like a wi-fi headphone device... probably some new efficiency tool for walmart employees or those stuck in the cubicle jungle... ie. a one-way wireless audio up-link.. drone gear... that will sell like wild-fire to all the pop music fans... or maybe just a wireless headphone setup... possibly involving some sensor feedback...
