Sorry lol, had to take a call.
This is where to go when you first open PowerPlayer
Then after click sound effects, you can fix here bass and other stuff
I'm using PlayerPro 2.35. The latest is 2.42 but hearing has some bugs, so am sticking to the one that works for me.
Alternatively, you can try Winamp or some others maybe - then let us know which is good ^^ hehe
