Bought lifetime premium when it went on sale to get the full use out of it, and it's absolutely amazing. I use it in tandem with my phones equalizer, my headphones equalizer and any piece of equipment that has an equalizer on it, want to talk about crystal clear audio and high audio quality that's the way to do it. I enjoy that it saves the presets, the only issue I have and it's very rare but the run in background function fails at rare times. 5⭐️

I've used this app for a few days now on my OnePlus 11 5G. My initial thought was that it would be as faulty as the rest, but I must say that I am very surprised! This app alone has made my phone sounding from Terrible to absolutely amazing! There are even many options you can use to completely customize how the app will work behind the scenes or for music only, etc. I highly recommend to use this app, it is only $4.99 to unlock the true potential of what your speakers should really sound like!

I've used equalizers in the past and I wasn't a big fan of them. I decided to try one again because my music sounded so low, and I couldn't hear the amazing instrumentals, or the instruments would drown each other out and it would sound like I had water in my ears. This is the best equalizer I've used in forever. I love the preset "treble boost" option, it's perfect for almost every song I listen to, and there's an obvious difference when the equalizer is on and off. I am in love with this app.

Works perfectly and allows me to use my different music, podcast, or other audio apps as well as YouTube and other online media with no problems at all. Offers plenty of adjustments to dial in the perfect sound for whatever I'm listening to, and also many great preset eq options. The bass & volume boost is great too. Sounds good with headphones or on my home stereo. It's a must have on all my devices now. Absolutely the best option available for this sort of thing I've found so far hands down.

Thoughtful design, generous features with minimal ads, and great sound quality. The automatic profiles you can create are such a smart idea! I have... Thoughtful design, generous features with minimal ads, and great sound quality. The automatic profiles you can create are such a smart idea! I have one for my phone speaker (volume boost), one for my Bluetooth ear buds for a better sound, and one that applies only some base improvements to any wired headsets since they can't be identified uniquely. I can get more specifc with profiles for my casual non-isolating wired buds, and one for my nice IEMs. Not a single regret downloading this one!

This app is extremely useful and has been working exactly as described. I can apply a very fine tuned EQ to any media in any app I'm using, YouTube... This app is extremely useful and has been working exactly as described. I can apply a very fine tuned EQ to any media in any app I'm using, YouTube, Spotify, etc. I love using it with my Audio Techica ATH M40x headphones and EQing them just right for the music I'm listening to. Even with my cheaper Bluetooth headphones it makes a big difference. If you are a discerning music listener and want a simple and effective way to get the most out of your phones music, this is the app for you.
