wireless microphone necklace ?

[Gints Klimanis]

Hi,

I don't have a picture of the wireless microphone necklace I noticed
on the UFC Reality TV show. Would anyone know of such a product ?
I combed the BH Photo wireless microphone section to look for
the product. From what I saw on the TV show, the microphone
had a black cord with a silver microphone section that hung
horizontally between the throat and the sternum. At first,
I thought this was some sort of UFC necklace until I realized it
was actually the mirophone when a fighter showed his backside
to reveal the wireless microphone transmitter pack fed by the
black cord.

Thanks,

Gints
