I would like to buy a speaker dock for my son. Ideally it would charge and play through the micro-USB connection (is this possible?) Ease of use and easily identifiable buttons would be an advantage. It would be used bedside so lighting is limited. He is adult but immobile so once he is in bed he is there until someone hoists him out. Audio books and music help pass the time or aid in getting to sleep. Any suggestions?
EDIT: As suggested below by kahn I can accept the need for Bluetooth or aux connection as long as it is charging as well.
As far as I'm aware, no such product exists. You can play audio out of micro-usb, but you need to use an app like USB Audio Player and use an external digital to analog converter. Speakers with bluetooth connectivity would be your best choice, and possibly speakers with an aux-in connection if a cable connection is acceptable.
