When it comes to listening to music on your iOS device, Apple has some built-in equalizer (EQ) settings within the Music section in Settings. However, if you're looking for even more customization for how your music sounds through your favorite pair of headphones or earbuds, then you should consider a third-party EQ adjusting app for iPhone and iPad. Here are some of our favorites!

How to adjust EQ (your music equalizer) on your iPhone or iPad

Boom

One of the best EQ adjusting apps on iPhone and iPad is definitely Boom. Personally, I use Boom on my Macs to get the best sound, and it's also a great option for the iOS platform as well.

With Boom, you get a bass booster as well as a 16-band equalizer and handcrafted presets. You can even create 3D surround sound, which works with any pair of headphones. There are 29 handcrafted EQ presets, including Dubstep, pop, and so much more — no matter what kind of music you're into, one of these presets is sure to amp it up! But if the presets aren't your thing, you have 16 different bands that you can fine tune to your own liking.

Boom works with your current music library, or you can stream Spotify or TIDAL through it as well. The app also has access to over 40,000 radio stations and podcasts too, if that's your jam. The interface for Boom is beautiful, and the app itself is just super easy to use.

The initial download of Boom gets you a 7-day free trial. After the trial is up, you'll have to get a subscription to continue enjoying unrestricted access to all features, which starts at $3 a month, or $15 annually. There is also a lifetime pack that costs $40.

Equalizer - Bass Booster

With Equalizer: Bass Booster, your perception of music on your iPhone or iPad can change! While it doesn't quite match up with what Boom offers, you can still get a 10-band custom equalizer and 16 presets, with the option to create and save your very own custom settings for quick access.

Some of the other useful features of Equalizer include independent equalizer amplifiers for low bass and high treble frequencies. There are even separate settings for Hi-End or Hi-Fi audio equipment, if that's what you're looking for.

Like other apps, Equalizer has a premium version that you can unlock via a subscription ($5 a month or $30 annually) or as a one-time $41 in-app purchase. Premium features include 2x presets, 3D sound, reverberation effects, bass boost, and more.

Evermusic Pro

For those who are looking for an EQ adjusting app that also doubles as a standalone music player, then Evermusic Pro is the one for you.

With Evermusic Pro, you can download your music library directly into the app for offline listening. Evermusic Pro supports the most popular audio formats, including: MP3, AAC, M4A, WAV, AIFF, and M4R. With your music in Evermusic Pro, you can upload them to its own cloud service and free up some space on your iPhone, which is a bonus.

As far as EQ adjustments go, Evermusic Pro has its own built-in equalizer with presets for the most popular music genres. If there isn't a preset for your preferred genre, then you can create your own preset with the manual equalizer settings, and change the preamplifier gain if you require the music to be louder.

This one is definitely more of a music player than equalizer, but it gives you options.

Equalizer Fx

When you want a simple EQ adjusting app that does a little more than the native iOS one, then you download Equalizer Fx. This app lets you improve your music or audio quality easily.

With Equalizer Fx, you get a variety of equalizer presets based on music genre, or you can customize your own using the 7-band equalizer controller. And if you want more bass? No problem! There's a few bass boosting effects, DJ transitions, over eight gorgeous EQ visualizations, and more. You can also access your cloud music library and play offline, so it's even useful when you have no internet access.

Have a lot of music in various audio formats? Flacbox should be able to handle it with no problem — this app can and will open almost any audio file on your iPhone or iPad.

Flacbox allows you to play your music directly from your cloud storage (all popular services supported), home computer, external flash card (if supported with an accessory), or you can download your songs for offline playback. The professional equalizer in Flacbox has several different built-in presets, or you can customize them and create your own for your music. There is also a preamplifier gain setting if the music isn't as loud as you'd like it to be.

Flacbox can play pretty much any audio file you throw at it, and it has a powerful equalizer that lets you customize your audio the way you like it.

Razer Opus

If you have the cool new Razer Opus headset, then you should definitely have the Razer Opus app on your iPhone or iPad. The Razer Opus app helps you get the most out of your Opus headset by changing the EQ modes that it currently uses. There are five presets: THX (default), Amplified, Vocal, Enhanced Bass, and Enhanced Clarity. You can fine tune each preset setting to your desired preferences, and even control the auto-pause and auto-off functions of the headset itself.

This app only works if you have the Razer Opus headphones, which we highly recommend.
