I was desperate and bought these earbuds from an airport vending machine, big mistake. They supposedly turn on automatically if you remove them from the case, that did not happen. I charged them fully before trying to use them, according to the light indicator they were fully charged but were still not turning. Since then I have charged them multiple times just in case and they still don not turn on.
The battery life isn't as good/long as suggested. Calls are not totally clear on either end BUT they get me through my work day listening to music so I like them.
