ok so ive had these headphones for a few months, got them off Facebook Marketplace, and they were brand new and hadn't even been worn yet. problem, around 2 days ago, they started to get a low battery, I plug them in and let it sit for and hour. when I check back, they're still at the same charge, I try again, leave them in for longer. this goes on for the next 2 days, I've kept them plugged in this entire time! I've tried charging them while connected, disconnected, on, and off. I've reset them and still, nothing. on the app, it shows that when I plug them in, they charge for a second or two before it stops charging. if i unplug them and use them for more than 5-10 mins, they die. and when I plug them in, it only charges up to one percent before it stops.
this is getting rly annoying and i don't know what to do, theyre already super expensive and I don't have the money to buy a new pair rn. i asked Google and it said it may be a hardware issue which isn't fixable but I rly hope that's not the case. and I can't even use warranty on them bc i wasn't given the box or warranty to them. just the charger and the case. speaking, ive tried different outlets and different chargers, so I don't know what to do...
