How do you know it is 80 dB? Is it dBA? Most people are not very good at guessing a level.
If you’re listening to music at 80 dBA for an hour, I think most guidelines would say that is safe. OSHA says you can safely have 90 dBA for 8 hours a day. This guideline is a bit dated and possibly assumes that the background noise one experiences for the rest of the day is lower than it actually is, but with a 10 dB safety factor and 6-7 hours in difference of length, you are likely fine if you trust OSHA.
This person does not trust OSHA
He's probably got an app on his phone that tells him.
If you connect any Apple headphones/AirPods to an iPhone it'll show you the dB level in real time.
The Sony app does the same for Sony headphones.
