Exactly what the title says. No this is not a troll post. There was some hardstuck water in my Holas which sunlight couldn't remove.
While I knew that my Holas have a N52 magnet inside them and that this could go horribly wrong because of the Faraday's cage, I thought just 2-3 seconds of microwaving wouldn't do anything. Also had this exact thought running in my mind "bad things don't happen to me" right before putting them inside. I was in semi-denial.
The driver tore off in a somewhat audible boom and now the right one doesn't work. The cable is fine because I didn't put it in the microwave, but the washing machine destroyed the mic last month and now it responds in flat noise.
Luckily they were worth only $20 but I'm still a student so it was somewhat major of a loss. In need of advice if recovery is possible.
TL;DR: Don't microwave your IEMs.
You are clearly knowledgeable enough to know how drivers and microwaves work, yet stupid enough to not have some common sense. Metal absorbs much more energy than water in a microwave, so it wasn't going to boil that off anyway. Likely what happened is a high current being induced with some combination of the coil overheating and burning through. Usually we call this condition as it relates to electronics as "fcked".
