| + | [* black] At first, I wasn't sure about the solder balls. Then I realized they anchor the USB and Power Interface pins on the outside of the Headphone to the internal circuit board. |
| [* black] I had to used a solder iron to remove the solder balls, so that the internal interface circuit board could be removed. I had to also remove solder from the speaker wires to free up the internal circuit board. | |
| - | [* black] The internal circuit board was also attached a MEMS Microphone that appears to monitoring the Speaker Chamber of the Headphone, since it was faced in. I had to remove the outside panel with 'R' on it to free up the MEMS Microphone. Once the MEMS Microphone was freed, the interface circuit was free to pull out |
