So to start off, basically what I'm trying to do is use my 3.5mm headset with awesome sound on my Xbox 360. I want to use it as a headset and to pickup game audio, so I need to have it plugged into my controller and into my TV.
If you're unaware, 360 controllers take a 2.5mm plug, but converting that is simple. My problem is finding 3.5mm couplers that also support the headset's mic line. Here's a diagram I drew to show my original plan before I realized it's so hard to find the appropriate couplers/extenders.
