Skink   10 #1 Posted June 6, 2018 Had a little ML20 earpiece for my mobile phone when I am driving - its been great  But left it in the car for a few months while I was using train and now it doesn't seem to be working properly - plugged in the red LED flashes, if I turn it on the headset tells me its on and battery is high  but unplugged it does nothing - guess its battery (not replaceable?) and there is no reset button?  Anyone point me in the right direction please?
