BlackShark Pro charging cable

my headset is working fine, but my charging cable is not charging my headset when it is connected, i have tried several different usb ports both hub and on my computer and none of them hold a charge, it only charges when i have the cable resting a certain way so im believing its the charging cable it self but looking on the cord i cant see anywhere there would be damage maybe a flayed wire cause keeps giving the disconnecting connecting sound
