Thanks Mel. It's just a shame you have to take the headset apart to do it. They could have put a tiny on/off switch or reset button somewhere where the lens enclosure is, that directly isolates the battery. I'd hate to think of how many headsets are ending up in landfill with lithium batteries onboard.
It's the same with all modern devices now. The battery is so much harder to get to than is need to be. It's one of my pet peeves, that no thought is given to making it easier to disconnect the battery.
It's a scary thought all right.
