I wanted to post a followup to my ant problem, lest my absence in this thread be construed as my becoming their fodder.
First of all, let's recap the lovely outside video (thanks Steve for hosting the file):

After some back and forth with Jack Wu - who has been extremely supportive throughout this ordeal - it was decided that I should attempt to clean them up prior to any shipping considerations. With some insights and caveats provided by Purrin and Spritzer I was ready to undertake this task.
First order of business was to pick a workspace - my usual one inside the house was out of the question because the living ants, so I chose the garage floor, as it would also double as an excellent squishing surface for any stray insect. I unrolled a few rows of paper towels, and then removed the phones from the sealed bag in which they had spent the last couple of days. After squishing any ants jumping ship with a piece of paper towel, I picked up the ones running on the phones and cable with a packing tape - I didn't want to soil the unit.
I removed the pods from the headband, then the pads from each pod. Here's what waited for me under the right pad:

Here's a photo of it as well:

After removing each part carefully so as not to pick up any ants, nor damage the phones, I got down to driver level. I squished straying ants, and wiped off the remaining ants from the metal frame outside the garage.
I then prepared for the reassembly, and took photos of most steps. I cleaned up with alcohol where applicable, and dry wipe where I thought it wasn't safe. The dust covers were not touched in any way, only the plastic driver frame on the outside.

Final product:

I'm happy to report that they sound great! But I still have that skin tingling sensation when I wear them, and still take them off every once in a while to look for ants. Brrrrr.
