During normal use my Blackshark V2 pro ran out of battery and even though it has been plugged in for 20 minutes it is no longer charging, wont turn on, and doesnt show a charging light.
I bought the headphones in 2021 so they are no longer in warranty.
They have been really inconsistent while charging recently as they seem to rapidly make the connect and disconnect noise at random while plugged in.

Is it most likely a cord or headphone problem? I don't have any micro USB cords lying around so I cant test it.
