It survived being laundered on two occasions and succumbed the third time. No, it wasn’t an experiment; it’s just so small I kept forgetting it in a cargo pocket.
Kudos to SanDisk for it holding up to such abuse. In fact, it still works when connected to external power and the tracks weren’t even lost. So presumably only the battery actually failed. Amazing.
So, now I am wondering whether to try replacing the battery or to just relegate it to non-portable duty in the car or home receiver… thus rendering it undead.
