I am having difficulties setting up my S4's and my Cowon J3.. I cant exactly get the sound i want. i am new to the whole JetEffect 3.0 Equalizer. since i am a former user of the iPod. I listen to mainly just Alt. Rock, Metal, Punk etc. Im trying to get a really balanced sound. I want to be able to hear every instrument clearly. From the bass to the vocals. Its hard since something always seems overpowering. i.e The bass is very strong and you cant really hear its tone, while the treble sounds good. Or the instrumental part sounds really balanced but the vocals are lacking. I am really new to the Cowon j3 and I don't really understand the purposes of the BBE and the MP enhance, 3D etc. Help!
