This article explains how to turn on Sound Check on the iPhone to adjust each music track to the same volume. This information applies to iPhones with iOS 14 through iOS 10. Why Use iPhone Sound Check Setting A problem you are likely to face when listening to digital music on your iPhone is the variation in loudness between songs. Inconsistencies in volume levels between songs develop as you build your collection. Given that the contents of most digital music collections come from different sources, including digital music download stores and music CDs, you'll eventually find yourself frequently adjusting the volume level. You don't have to deal with this inconvenience on the iPhone. Instead, use the Sound Check option to play your songs at the same volume. With Sound Check, the iPhone measures the loudness of all the songs you synced to your iPhone and then computes a normalized playback volume level for each one. This modification in output volume isn't permanent, so you can revert to the original volume levels at any time by turning off Sound Check. How to Turn On Sound Check on iPhone Sound Check is disabled by default, but you can turn it on if you know where to look. To configure Sound Check for the iPhone, follow these steps: On the iPhone Home screen, tap the Settings icon. Scroll down and tap Music. Turn the on/off switch next to Sound Check to the on/green position. After enabling Sound Check, press the iPhone's Home button to exit the Music settings and return to the main screen. Tap the Music icon on the Home screen to play your songs and playlists adjusted to play at the same volume. You can also use Sound Check on a PC or Mac running iTunes. Was this page helpful?
