My headphones just suddenly stopped working

So i got the mpow 059 for christmas and I loved them. They worked like a charm but one morning I woke up and they had been charging overnight as I could use them, but when I went to turn them on nothing happened. I held down on the power button for about a minute and the headphones didn’t say they were on and the light on them didn’t turn on. So I checked the nice canceling switch and nothing happened. So I thought maybe it was some weird charging issue so I plugged them in for about an hour in a different charger in a different room and when I tried to use them nothing happened. But then about a couple of months later I go to try to use them again and for some reason the noise canceling works… but that’s it… they won’t turn on.
