When you pair your Bluetooth earbuds and one hasn't charged
ALWAYS GETS ME AAAARRRRRRGHHHHHHH I make sure I disconnect them from all devices; I make sure they are well positioned in their cases; that the charging lights are on etc and yet.... they disappoint me like this...
I have a five-year-old pair and cannot imagine how someone would lose just one. They live in the case when not in my ears, so they stay charged. Losing single one and not the whole case baffles me.
