Ive tried a few different sets of headphones on the S7800 and everything is the same. The output is quite tinny, no depth, no bass at all. I know the headphones are way better than what is being delivered so must be the system.
My question is, can you do anything about the sound output. Are there any apps out there which can sort of give an equaliser effect but not just for media players. Maybe a root app that allows you to change things?
