How to actually turn off the headphone safety features?

Settings>Accessibility>Hearing>Audio/Visual>Headphone Notifications = OFF

When done, restart your iPhone.

The post by ProustGuilio is probably referring to the notification feature --> Headphone notifications on your iPhone, iPod touch, or Apple Watch - Apple Support

Settings > Sound & Haptics > Headphone Safety > Reduce Loud Sounds on/off

thank you, finally... "headphone" notice when in fact, phone is connected to speakers, wasted time looking for this and searching different arrangements of options

thank you!

do you know how to turn off google perpetual "sign in" every time I use "contacts"?

google isn't even my primary email but, apple and everyone else making love to google means, I can't eliminate it completely... I was deleting old contacts yesterday, every contact I looked at, I had to close the google message twice...

i find this feature absolutely ridiculous, because at 65 I still have good hearing and Apple thinks I am not smart enough to know what’s good for me. As an 19 year old Air Force plane mechanic, I wore my ear protection, so this is a bunch of BS, I know when something is too loud. My problem is not head phones, it’s when I hook up to my garage stereo or my wired CarPlay. Then I just have to crank the volume on something else to get a decent sound and the dum *** iPhone with at times turn down the volume. And I know it’s Apple doing it, because plugged in to CarPlay is one volume and Bluetooth is another, with Bluetooth I have to turn the volume down. Already talked with an Apple advisor and no help.
