The buds should last 2-3 hours of constant use before you need to pop them back in the case to charge up.  Again, the charge indicators on the case will flash the top segment until the buds are fully charged, where the red LEDs on the buds go out and the bar graphs will actually switch off, as the buds power down.  This last stage of trickle charge takes longer than getting from the bottom of the bar graph to the top, if they have completely discharged.
