The Mi Civi3 can use wired headphones, and the phone is equipped with a 3.5mm headphone jack, which allows users to plug in the wired headphones for a more stable audio connection. Wired headphones generally provide higher quality sound and lower latency than wireless headphones because the audio signal is transmitted directly over the headphone line. In addition, wired headphones can also avoid the battery life problems that wireless headphones may face, so that users can enjoy music, video and other entertainment content for a long time.
