Make a set of sneaky earbuds that record what you hear. They create a binaural effect
when played back wearing headphones.

  • Thumbs up if you heard the "Solder!" scream in the background. ^^

  • @jacisin85 8

  • Kipkay don't need no human friends!

  • press 8 for i did it

  • @nrdesign1991 Ahh, I see. I didn't notice that.

  • @gosmiti He just solders the two wires to one connector.

  • @nrdesign1991 The jack he's using has 3 contacts: Left+, Right+ and Common Negative. That way you get two seperate audio channels. :)

  • @ffKingcreole Indeed, It's a stereo jack, but both microphone outputs seem to be soldered to just 1 pin, meaning you'd get, at best, summed mono output on either the left or right channel. Also, these electret mics need a power supply, around 3-9V supplied via a suitable resistor and then capacitive coupling to remove this DC from the output, so the only thing I can think that you could use this with is a PC soundcard mic input, which has this supply, but is mono anyhow!

  • What you're soldered is a mono microphone, which will not create a binaural effect
