Just to be clear, are you suggesting that wearing a hat causes some sort of damage to one's health? And further than that, a hat that kept one's head as warm as two one inch pieces of plastic? Obviously I don't have data to back it up, but I can't imagine even gluing a pair of AirPods to one's face for one's entire life would make any significant impact on lifespan. Other than maybe all the glue. EDIT: And if you're experiencing excessive heat from earbuds (which I would say would be essentially any amount of heat - they shouldn't really put out any noticeable heat), you probably have severely faulty earbuds and should get them replaced.
