5 stars: This app is extremely essential for my needs. I do wish some of my headphones were apart of the AutoEQ but the Graphic EQ works well. So, it's fine. I had slept on the reverb feature because from my experience, the reverb sounds artificial on other EQ apps. Not this one. The reverb sounds amazing and flow with the songs. I'm hoping in the future there will be more enhancements and improvements on the reverb to get even better.
4 stars: I bought the VDC file for my headphones for usage with Viper4Android. That one has been on and off for me and sometimes lead to ear damaging distortions. I just paid for this app, because it does what I need: reduce the heavy bass from my headphones and add a better soundprofile without effort, needing root, etc. Only improvement I would like is to have the notification hide from the task bar.
5 stars: superb. I have been looking for a system wide eq, but that's not happening unless I root apparently. This is the closest that I could get to \
5 stars: Holy jezus this app is so amazing! I can tune everything, every sound device can be customized each and now they're sounding much better! My phone speakers too. This app is way better and more than every another equalizer app. And easy to use (excluding bottom three functions).
5 stars: I really like it, sounds so much better on my melomania 1's. Unfortunately, there is no profile for V-Moda Zn in ears. It would be great if there these will be added. Same counts for the Pi...
