Q&A #13 - Are IFB/IEMs essential to own?

This was a question from one of the previous Q&As about how essential i think IFB/IEMS are. I took this to mean buy some to use in equipment on many jobs. For that reason I would say it wouldnt be something I would look to buy early on but they do come in handy for bigger jobs or commercials when clients and agency are wanting to listen in while watching video village.
