Has good open back headphones and subs to apple music for hires/lossless; listens to YT music on BT earbuds most of the time 🙂

6-8 hours most days in the office and then usually 4+ more hours listening to videos on my tablet. I usually fall asleep listening to something too.

Safe is 8hrs at 85 dB, double/half that time for every 3 dB decrease/increase.

Similarly apparent power where you often treat watts and volt-amps like they're the same when they aren't. AC is hard 😂
