When being charged, earphones have red light flash slowly and screen on power box displays power quantity in earphones.(For example, the first light flash indicates 0-20% power; the second flash, with the first on, indicates 21%-40%; and so on, the fifth flash, with the forth on, indicates 81%-99%)
