Interesting. I didn't know that additional earwax production was the body trying to protect from hearing damage. I had to give my headphones a break after using them heavily for a couple of days because of this. I assumed it was because I was not used to wearing headphones and that they restrict the airflow to the ear (thought maybe the body becomes accustomed to wearing them over time).
I knew my ears are sensitive, but they must be more sensitive than I thought considering how low I have my volume set.
