Do you feel like earbuds, headphones or external speakers aren’t doing your music justice? The default equalizer balance in iOS is flat, and while iOS has some decent EQ presets, there is no way to customize levels without purchasing a third party app. This is where iTunes comes in with customized equalizer levels. Some iPhone, iPad and iPod touch owners have inferred that changing the equalizer levels boost sound quality in every way possible. I tested it out, and it turns out that it does.
To customize equalizer settings on your iDevice, you have to first adjust them via iTunes. This will work on both Mac and PC. Open iTunes and click View >> Show equalizer.
In the equalizer, start adjusting settings to where you want them. An effective place to start is what one iTunes user claims as the Perfect Equalizer Settings.
The setting for “perfect settings” are:
“db +3, +6, +9, +7, +6, +5, +7, +9, +11, +8 db”
Once you have all of the levels set how you like them, click the drop list and select Make Preset.
Name the EQ presets whatever you like that makes sense to you.
Now you can close the equalizer window, just remember what you named it.
Back in iTunes, plug in your iPad, iPhone or iPod.
Select All (Ctrl + A) of the songs in your device’s music folder, and then right click one of them and select Get Info.
Click the Options tab and then scroll to your Equalizer Preset. Make sure the equalizer box ix checked, and then select the custom setting you set up.
Click OK to exit and save changes.
iTunes will take a moment to sync. Once it is done, enjoy the groovy new life you’ve infused into your music — even if you have mediocre earbuds that Apple gives you.
Note: If you have a preset equalizer set in iOS it will override your custom settings from iTunes. You can clear this by going to Settings >> Music >> EQ >> Off. Once off, your customized iTunes equalizer settings will start working.
