Sadly, the earcup's contents weren't as plentiful as I had hoped. Housed inside are the lithium battery, noise-cancelling microphone, LED control circuit, and power/charging circuit.
After completing a visual inspection the circuit board for any signs of component failure (discoloration, burn marks, melted exteriors, etc.), it was time to look to the other earcup for answers.
