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.
I think you missed something here. Do you know if you put a tiny water drop in the microwave and it'll never heat up? It's too small compared to the wavelength so it won't work. So even if the microwave wouldn't damage your IEM, this method wouldn't remove the water either.
A good solution is to put it in a sealed box with anything moist absorbing substance, like silicone gell or calcium oxide. Because the relative humidity of the surrounding air is going low, the water in the IEM would eventually evaporate.
