Yes after a while the green led turn off but in my case the next day the earphones are totally drain...I am wondering about this as well as I have seen a few reviews reporting this, like the headsets never stop charging when they are in the case. I just got mine today, so not sure yet, but I can tell you that after the headphones are fully charged in the LEDs turn green, they stay on for a little bit and then go off totally, so I am assuming that no further drain should be happening at that point. Others were indicating that the LED lights never seemed to go out, which is not normal operation.
