realme phones have two types of earphone jacks: 3.5mm jack and a Type-C jack.
There are two types of Type-C earphones: digital earphones and analog earphones.
Analog earphones:
Direct analog signal input. With the help of the built-in DAC of the smart device, the digital signal is converted into an analog signal that can be recognized by the human ear. After transmission and amplification, it is output to the earphone. The 3.5mm interface earphones we usually use are analog earphones.
Digital earphones:
earphones designed with the digital signal interface, and direct digital signal input.
