Warning: heating earbuds batteries to over 300F also causes fires
Reading this tells me the author has absolutely 0 idea of how physics work and is nothing but a blogger of consumer grade equipment. People like that should refrain from trying to understand how science or scientists work.
- Obviously, physics aren't done in Fahrenheit.
  
  Had to laugh at your comment. Not that it matters in this case, your ear buds are not going to magically combust at just 150°C
  
  They'll not combust, I'd hazard a guess that air pods are made from ABS which has a glass transition temperature of 105C, so they will melt.
  
  Dimethyl carbonate boils at 90° so the battery could pop
  
  Good news everybody!
  
  ABS which has a glass transition temperature of 105C, so they will melt.
  Well, they’ll deform. ABS won’t melt at 150°C, it’ll just become soft and flexible. But yes, it’s a bad idea for your earbuds.
- I think you mean they shouldn't write authoritatively about things they don't understand, because what you said is really gate keepy. There's nothing wrong with learning.
  
  People shouldn't compare things to gatekeeping unless they can build a cast iron gate
