Anybody familiar with the headset connectors used with Vokkero sports/referee intercom systems? According to the Phonak (headset supplier) they are made by Fischer, but as usual there's no part # and the website isn't very helpful.

We're hoping to avoid putting a lav mic on referees for the Big Ten games we work, instead wanting to make a Y-cable to get a signal from the intercom headset they're already wearing.
