In a professional or technical context: IFB can also stand for Interruptible Foldback (or Feedback), which is a system used in broadcasting, filmmaking, and video production for one-way communication from the director or assistant director to the on-air talent or remote crew. This system allows for cues and directions to be given in real-time, typically through an earpiece.

I'm still skeptical of the earring theory (feels like it was planted to discredit us) but we'll see.
Could it be an IFB?

Sounds very possible...
Thanks!
