Bose headphones intermittent sound?

Do your Bose noise cancelling headphones have intermittent sound in one ear? If you have a soldering iron, this could be an easy fix.

I can't believe how cold/dry those solder joints look directly from Bose! When I repair my headphones, I'm going to flood every joint with some leaded solder. I would have expected a broken wire from flexing...not a junk solder joint!
