Check your headphone audio levels on iPhone
While using headphones with iPhone, you can check the audio level by viewing the Hearing control in Control Center. In the Health app, you can review the history of your headphone listening habits.
If you listen to loud headphone audio long enough to affect your hearing, iPhone automatically sends you a notification that you should turn down the volume. After you receive a notification, the next time you plug in your headphones or connect them using Bluetooth®, your volume is automatically set to a lower level. You can turn the volume up again if you choose.
Tip: To review the details of a headphone notification, tap Browse at the bottom right of Health, tap Hearing, then tap Headphone Notifications.
