So I listened to these headphones at max volume from my laptop and they were super loud--what I would think of as WAY too loud for my 5-yr-old, too loud for me even. I did attempt to measure the output using a phone app--just held one of the headphones up to my phone's mic--and at max volume it did measure 85 decibels. No idea how accurate that method of measurement is. Still, I actually have some hearing loss from attending way too many punk rock shows in my youth, meaning my hearing is not very sensitive, and these headphones seem super loud to me. There is no mention whatsoever on the packaging that these are decibel-limited headphones, and there is no paper insert in the packaging that suggests there is either. All in all, I'm just not confident these are safe.
