I dropped and it came apart

Solved it.
If you need to take it all the way apart, here's the scoop:

Get the top cover off by popping it up at the hinge side (this is what pops when you drop it)... then at the charging end, slide the top towards the hinge to slip the clips out from under something.

the folding mic tells the board it is open by a small z-shaped piece of plastic. The skinny end of this fits into a tiny hole in the bottom of the case and the fat side slides up and down in a little round space over on the side of the case. There is a rubber button with a dark piece that sits on top of the round space. The dark side of the rubber piece presses against a round circle on the circuit board and tells it whether the mic is open or closed. Once you put it all together, you have to press the board down pretty firmly to tell if it is all working.

Then put the volume buttons back in place and slide the top back on.

Its really really an easy fix. the unit snapps apart, starting from the end on the oposite side of where the unit is charged. Don't take it farther apart than you need to slip the button back in place on each side and snap it together. If you need more space you can take it apart farther however be careful not to remove a little plastic piece that is used to turn the unit on when the boom is open.
