Under Desk Headphone Extension Cord

A simple project that birthed not long after I finished my macropad. With the amount of zoom meetings I've been having along with my MacBook just sits on a desk, clamshell mode, behind the screen, it'll make it easier if I can just plug my headphone directly into the desk without needing to reach around and what not.

This is a quick and simple project but you need to solder tiny wires. Here are the things you need:

  • TRRS cable, it can be extension cable, but you'll need to figure out how to mount it.
  • TRRS female connector, plate mounted if you want to use my STL
  • Mounting plate STL
  • Heat shrink tube to cover the soldering job

As you can see in the video, I made note of which pin correlates to which wire. I believe this should be universal, but feel free reconfirm this on your own.

  • Tips -- 2 -- blue
  • Ring -- 3 -- green
  • Ring -- 4 -- red
  • Sleeve -- 1 -- gold

Next all you need to do is:

  1. Solder the wires
  2. Cover it with heat shrink tube
  3. Mount the plate on to desk
  4. Mount the connector on the plate
  5. Plug everything

Done and done.
