It's amazing I use it all the time whenever I'm listening to music!
Much better sounding music When I was i using headphones with my tablet without this app/widget my audio sucked, but with it much better sounding. This is a must try for anyone who wants better sounding audio. This has even made listening music on my tablet's built in speaker more enjoyable. The only problem have with this app is that bass and virtualized don't seem to work. Other than that no issues. The widget is really easy to use and does not take up a lot of space since it is about the size of an app icon.
So nice I love it. It's a great app. I searched desparately for apps to enhance my music player and I have found none that beats this one. I have been using it in lower Android models and is superp but I recently got Android 6.0 and it started having some issues. I just wish the producers of this awesome software could do something to upgrade it. I really can't do without it. It's mind blowing.
