In case anyone is wondering, I just got my replacement pair of TF10s today. They seem to be in working order, and the turnaround time was faster than I expected(they came in a bit more than a week from dropping it off at a UPS store, I was told it'd take two).
Of course, I've been shopping for a possible replacement case since before then, and now with the case back I can do a comparison. Currently stuck between a Pelican 1010 and an Otterbox 1000 atm. The former seems to be a bit large for a pockets, the latter seems to be still a bit too small to give my IEMs some breathing room.
