I learned a lesson from these posts.
What's the follow up? How do USPS reply?

The conclusion:

Thaddy is sending them back to me, I will buy a replacement headband and install the driver units. fortunately the drivers still work.

Glad the situation is resolved.

I recently mailed a pool cue's shaft back to the manufacturer... and the box got there, but it had been cut open, the contents removed, taped up, and shipped on. I had insured the package, but they needed a bunch of paperwork from both ends filled out. I lost the receipt a bit after I figured what needed to be done, and am now SOL.

I don't think I'll ship USPS again, if I have a choice at all.
