Why do earphones go off after a while?
Prove your headphones, and then he's fully charged, and then he's off in a moment, especially with headphones, he charges very fast, you take an hour, and then he charges in a few minutes to full well, they're this fast charge, so it's just a moment and then it's off, you know?
Say that's the way it is

It should be caused by poor interface contact
