Part 2. How to Limit the Maximum Volume on Your iPhone/iPad/iPod for Your Kids
If the volume of your Apple Music on iOS 12 devices is too high, you can adjust the volume directly. Also, you can try the 3 ways to change it by EQ settings, Apple Music sound check and set a volume limit. The settings is more or less the same across iPhone, iPad and iPod. Here I will illustrate how does it work with iPhone.
Equalization settings will apply to the music played from Music app such as Apple Music or the iTunes songs that are synced to the iCloud.
Step 1. Open your iPhone and click "Settings".
Step 2. Find and click "Music" app and click "EQ".
Step 3. Open the opened windows, you can change the equalization which will affect the output volume too.
Apple Music Sound Check
This is a feature built into iPhone, iPad and Mac for adjusting the volume of all the songs of the album to the same level automatically.
If you don't want to keep turning the volume of your Apple Music up or down time from time, now it is time to enable it.
Similarly, you can click "Settings" on your iPhone, scroll to find the "Sound Check" option and then switch the button on.
Set An Apple Music Volume Limit for Kids
Even if you have changed the volume, your kids may still be able to adjust the volume by themselves. To prevent this, you can set a volume limit.
Step 1. Open the Settings app from your iOS 12 device like iPhone.
Step 2. Scroll down to the "Playback" category, there will be an option "Volume Limit".
Step 3. With the slider, you can set a volume limit. After them, not matter how did you adjust the volume, it won't exceed the value you have just set. Generally, it is recommended to set to 70% of the default maximum volume.
