It blasts mp3 songs with a quality earpiece (included). There is an equalizer in the phone! Easy as drag and drop to put music on the card. I have a Sony PC, laptop, video camera and MD player. My data completely flows now! With bluetooth, I already swapped data with a friend using an LG phone on Verizon; so there is nothing proprietary about the Sony phone.The camera is excellent considering the all in one functionality and the light on it is really bright. You could technically say it has a built-in flashlight!Battery life is great. After the initial charge, and learning all the buttons/menus/etc, taking pictures, videos and jammin' to mp3's the better part of the evening and all the following day, there is still a 3rd of the power bar left!The menu setup is very easy. I had all the functionality memorized by the end of the day. This phone has you covered in case your learning curve is longer. Anything that has a more involved selection, it will give you an "info" option for more details.I can rave about every other function of this awesome gadget, just waiting until end-of-contract to activate phone service. This is what I have been looking for since "convergence devices" hit the market.
