Step 2Determining the PCB Layout
From what I've seen of USB headphones, the basic control scheme and layout appears fairly identical. The particular USB set I used was an inexpensive Gigaware USB Headset sold at Radio Shack. Earlier models of this headset were complete garbage, so ask the dealer if these are the new revisions or not. The newer ones apeared to address all the customer complaints of the originals, and actually perform very well.
Use a small jeweler's flat head screwdriver to gently pry the top of the controller box off. It merely is snapped into place in this model.
Inside, we can see where the twisted shield and single wire from the headset mic are attached to the PCB inside the controller.
