I’m looking for a good music equalizer app for my LG Sunset phone running Android Lollipop 5.0. I want to use it with Google’s Play music app. I’ve downloaded about a half dozen, but none of them really work. Oddly, they work fine over a Bluetooth connection, but not when I plug headphones or speakers into the headphone jack. None of the EQs affect the music coming out of the headphone jack. Does anybody use an equalizer they can recommend?
