This is an informal vid on how to craft a DYI binaural mic.  To hear the full effect listen to this on headphones.

This is a budget approach to simulate the immersive effect one gets with something like the Neumann KU-100 mic. Don't for a minute think this $100 project can go head-to-head with the Neumann. But, it can give you a taste of the binaural technique.

The Roland CS-10EM product is designed to plug into a camera or location type recorder. The camera/recorder supplies the voltage to the condensers. However, I wanted to plug it into my Focusrite interface; therefore, we need to work out how to power the Roland.  Here is what you need;

Parts
2   10k resistors
2      2.2 microf electrolytic capacitors  (polarized)
2    1/4" female jacs
1    TRS 1/8" female jac
1    9v battery
1    spst power switch
1 project box to house the PS
1    Roland CS-10EM mic/earphone rig
1    mannequin head 

The first seven components are to provide power to the condenser microphones - Roland spec indicates they will work from 2v to 10v.

***this is NOT phantom power - 48v, as supplied by most consoles, will fry these little guys***

I have not provided a schematic as I don't want the liability; if the hookup is not self-evident to you then find a buddy that can figure it out, this is really fundamental. To get you, or yer buddy, into the ballpark

**the resistors are current limiting & 10k is what I had on my bench. Intuition tells me 2k would be a more suitable value but, meh, 10k works

**the caps are DC blocking & what I had on my bench.  If you don't have 2.2microf go lower (1 microf is prolly good) rather than higher values. Note the correct unit symbol is  µF  but that symbol may not make it thru YouTube's filters.  To be sure I used   two-point-two microfarad caps

**more work needs to be done on the PS as the jury-rigged one I used resulted in 60hz & other noises.  That said, and as it states in the video, I simply applied a noise reduction algorithm in post production... you can hear the effect of the noise suppression starting at about 1:30 

The head I used is PVC but styrofoam heads can be had at a fraction of the price.

Once you've worked out powering the Roland unit they need to be plugged into two MIC inputs. On your console pan the two inputs hard left & right. I had to use quite a bit of gain on the Focusrite input ... but... it sounds great.
