  1. 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.

  2. 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.

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

    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..!

  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.

  5. 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

    • Hi, i’ve also been looking for an app that will do this for years, I.e. equaliser that can adjust all audio that leaves the iPad/iPhone. Baffles me why Apple don’t just put adjustable EQ alongside the presets in Settings. Still can’t find one in 2021 ☹️. The search continues!

  6. 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

  7. 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.
