Use these iOS equalizer apps to adjust EQ for better audio quality

Best iOS Equalizer Apps

Music is one of the most popular activities for mobile devices, with millions of us listening daily thanks to the portability of smartphones and tablets. While the built-in native equalizer on iOS is great, the settings come as presets which is still kind of limited for users. Many people are looking for extra fun being able to precisely adjust the bass, midrange, treble and boost the sound.

Although you may think that the audio quality of your iOS device is pretty good already, thanks to its built-in equalizer, you might be pleasantly surprised by the difference offered with a decent equalizer app. Thankfully, Apple has given leeway to developers that want to create equalizer apps for iOS devices, and there are various EQ apps now available on AppStore.

How to access the built-in iPhone/ iPad equalizer?

As mentioned above, the built-in iPhone equalizer is more than enough to satisfy most of your audiophile needs. If you want to access and change some EQ presets on iOS, here’s how to do it.

Navigate to the “Settings” app. Scroll down to the “Music” app. Tap EQ, it’s under the Playback section. Navigate through the EQ settings to find a preset you’d like to use and change the settings in the app. Exit the EQ settings using the home button or gesture.

Is there an equalizer app for iPhone?

Yes, there are a lot of both free and premium equalizer applications for iOS, which can be found on the App Store. Unfortunately, some audiophiles have more bass demands from their device and want to tweak the sound to be to their liking while others want more acoustic sound. Below you will find some great Equalizer apps you can use to change your audio settings.

How to use the equalizer app on iOS devices?

Given that the native iOS app is made so intuitively that regular users can use it with ease and that the app is open to developers, third-party apps are also well-made to meet user demands, whether they are more or less tech-savvy. All apps have different features and user interface, but the available presets, intensity, and other filters are universal and easy to use.

These apps can adjust the sound to be just how you like it and give you more controls and settings to take advantage of. This will make your enjoyment of music more satisfying, whether you’re a casual listener or a professional musician.

  1. All Equalizer Apps are very nice for iPhone and I will download one of them. I am dame sure it would be very useful to my iPhone. keep sharing your ideas.

  2. I’m a heavy Plex user, and it seems that all of these EQ programs either need to plug into an application (i.e. BOOM: BASS BOOSTER & EQUALIZER), or play the files within their own app. Is there an EQ program that allows you to adjust the settings, no matter what player preferences you have? Or did I miss something in your article? Great review BTW. Thank you

  3. I’ve been trying to find a Equalizer App that I can use via my 2019 iPad and 3rd party music apps ( Mixcloud etc) as my Bose speakers are so Bassy, but can’t seem to find one, after many download attempts of other apps Boom, etc ☹️ Any ideas, pls? I’m just want to try the Bass, down, for every audio coming from iPad through Bose speaker. Thank you

  4. Hi there.
    Your review says Denon Eq App is absolutely free.
    No it is not. Unless Denon have updated their App in the App store, it costs 2,29€ to access the EQ.
    I just checked it. Correct me if I am wrong please.
    Your article is good and well detailed but should be updated.
    Writing this on 18th May, 2020.

  5. My email address was not uploaded when I wrote about the Denon Eq App. Here it is if you could reply.
    [email protected]

    Again, the Denon App for Equalizing music is not free on the iTunes page.
    It would be great if you updated your article in 2020..!

  6. Is there ANY equalizer app that controls ALL sound on the iPhone? These seem geared only for music. I especially need one that controls sound during phone calls. Thank you so much.

  7. I wonder if NikooPlayer also could be listed in this category? It include a unique stereo EQ and it could also gets your hearing charts and adopts its EQ levels to give a boost to where you hear less. It offers also tones of other music and audio enhancement features like speed, pitch, volume boot, reverb, echo, delay, sing along, binaural 3D audio effects, loops, etc.
