I plugged my headphones into my iPhone (via the Lightning to 3.5mm headphone jack adapter) for the first time in some weeks. I received a message asking me if I was using headphones to which I replied "yes".
A little later while listening to music, the volume automatically reduced and I received a notification stating “Volume Turned Down Based on your headphone usage over the last seven days, the volume has been turned down to protect your hearing”.
I wasn’t using Apple or Beats headphones so how could it know low loud my headphones are for any given volume level selected on the iPhone?
Looking in Health, it seems to think it know the decibel level:
