Ok, two things...
FIRST:
I'm not a seasoned production mixer, but I was on a set the other day and we were mic'ing up several scantily clad women with these "necklace lavs". They were provided by the rental house . The mic element was apparently hidden in a somewhat octagonal and metallic looking piece of jewelry worn around the neck. While I could not SEE the mic element, it was hard to tell if this was a homemade creation where someone glued the element to a necklace. The cable leading to the necklace was definitely COUNTRYMAN. A Google search for "any combination of "necklace-lav-countryman-mic-etc" yielded no results, just links to forums where other people asked similar questions. I contacted Trew, but no one had seen/heard of this. Why I didn't ask the gear wrangler from the rental house is beyond me.
SECOND:
I've recently started doing field fx recording again. Years ago I had built a ridiculous contraption/hat so with Schoeps capsules tucked into the brim with a cable running down my neck/back and going into a bookbag with a portadat in it. I heard recently that someone has devised a cool little setup with mic caps mounted on ear buds with split cable that will allow you to plug this device into a portable flash recorder's mic input for recording as well as a cable to plug into the headphone jack for monitoring. Does anyone use a system like this? Does someone manufacture one? Has anyone had success building their own?
Sorry for these newbie questions. I'd like to hear from the pros!
