There are many options available for binaural microphones. I've shown two options available here. I have used both, and am satisfied with the quality of each option.

The first option is the Core Sound Binaural Mic Set. These microphones are great for this application. Not only because they sound great, but because they can easily be mounted in the ear, or ear canals of your dummy head.

I use the Core Sound mics in all of my dummy head recordings.

For the purposes of this tutorial, I will show you how to build a dummy head using the Core Sound Binaural Mic Set. I will discuss how to mount these in the ears later on.

The second option is The Sound Professionals SP-TFB-2 Mics. This is the more budget friendly option. However, even though they're less expensive, these mics also sound great.

These microphones are designed to be worn in your own (real) ears for field binaural recordings. As you can see from the links on the left, they arrive with the mics mounted in plastic "in-ear" supports. I would recommend these to someone interested in also doing field recording using their own (real) ears.

The only hurdle with using these mics in your dummy head is that if you want to mount the mics inside the ear canal, you will have to remove the mic elements from the plastic "in-ear" supports. This is not difficult, as they are just hot-glued in place. I was able to remove my elements within a few seconds.

But I must warn you that if you're not careful in removing them, you may damage the mics. If you want to re-insert them into the plastic supports, you will have to re-attach them yourself.

Note: If you are planning to record using these mics on a system without "plug-in power" (included on certain mini-disc recorders), you'll need to also order the power supply accessory.
