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 running iOS 14 through iOS 10.

Why Use iPhone Sound Check Setting

One of the most annoying problems 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 will inevitably 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, it's no wonder you'll eventually find yourself frequently adjusting the volume level.

You don't have to suffer this inconvenience on the iPhone—you can use the Sound Check option to play all the songs at the same volume. With Sound Check, the iPhone measures the loudness of all the songs you have 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:

  1. On the iPhone Home screen, tap the Settings icon.

  2. Scroll down and tap Music.

  3. Turn the on/off switch next to Sound Check to the on/green position.
