So I have been futzing with my new S4s for the past few weeks and following folks advice around here and I can honestly say that I have ocassionally reached audio nirvana. With a little bit of messing around I can find the 'perfect' fit using one of the ear pieces. It's almost like the bass goes up 20% immediately. Unfortunately, it lasts until I move my head, bend over, chew gum, or anything like that. Don't even think about exercise. So my question is, am I doing something wrong? Or is that just the way it is? Thanks.
