On/Off switch not working
I have this great set of earphones since 2016, however in the past one year, the On/Off switch isn’t working - I can turn it on, but it cannot be switched off. The green light stays on and the battery will just drain by itself. So each time I need to use it, I’ll have to charge it and let it die by itself after it’s run out of juice.
Can anyone advise what to do?
