Head Worn Microphones

Written by Scott Parker

Behind the ear mics are called Ear Clips.

The almost finished product on Elize's ear. This clip was a touch big for her ear, so we added a piece of tape

We used a piece of heat shrink tubing for most of the unit. You can see we've used two pieces of 18ga. wire. I bought the wire at a plumbing supply store. They call it "hanging wire." The second two photos show the addition of Hellerman Sleeves to finish it off. After more trial and error, we've decided to go with just these Hellerman Sleeves for our future ear loops.

David Earl shared this photo with us and it became our guide. This ear loop consists of the mic, a piece of floral wire to hold the mic towards the actor's mouth and a store bought plastic ear loop. All covered with Hellerman sleeves. The part of the ear loop that goes down to the middle of the ear canal opening is covered with skin colored tape. We still have to order a roll.
Below, you'll find our first attempts at creating ear loops. We used tape before the Hellerman tool.
This is a headband type of setup. The headband is made from elastic string tied in a loop. The mic cable is attached using thin floral wire. The wire is wrapped around the mic wire, starting at the mic itself. Then the floral wire runs up the mic wire and meets the elastic. Thus joining the two. After all this, they are both covered with tape.

This is called an ear loop. We used a wire similar to a shirt hanger. You can also use shirt hanger very easily. As you can see, the mic is attached at the end. Then the mic wire is taped to travel over the ear.

The ear loop is adjustable to fit most ears. However, you may run into some people with very small ear lobes. This might be a problem for this type of rig.

Rock-n-Roll, here we come! It makes plain sense that the closer you can get the microphone to the mouth, the louder you can raise the volume. This headset gets the mic exactly where we wish. It's also very sturdy. This rig is not going to fall off during dance moves.

You can use shirt hangers and tape to create this setup.

One of our storage boxes. Custom made insert (foam rubber with cutout slots) cushions have slot for all the parts.

	The main slot for the transmitter.
	The slot is extended to hold the antenna and the mic cable. At the end is a hole for the mic clip.
	The slot on the right holds all the little foam mic covers.
