Okay I just recently bought the Corsair hs70 about 3 days ago and I fully charged them the first time and the flashing light would blink yellow but I charged them the second time and it gave me the green light that they will fully charged but now the light is blinking red, does that mean they're going dead already or what's going on with them because I just got them off charge and it was a full green charge. I hope nothing is wrong with them because I honestly like them
