Headphone Safety
Most people call this limiting how loud headphones can get.
Your iPhone measures headphone volume over time, warns you when exposure is unsafe, and can cap the maximum level.
This setting is present on your iPhone.

Questions people actually ask
- Why does my iPhone lower my headphone volume?
- Headphone Safety has detected sustained loud audio and reduced it to protect your hearing.
If it is not working
- In some countries the notifications are required and cannot be disabled.
- Screen Time restrictions can lock the volume limit so a child cannot change it.
- Headphone Levels in the Health app shows your actual exposure.
