Just connect it to the headset interface.

The Ruilong version of Xiaoxin Pro13Pro is equipped with two full-featured TypeC interfaces, supports PD fast charging, and also has a USBA interface and headset interface.

The Xiaoxin Pro body is made of aluminum alloy. The A side has no decoration except the Lenovo trademark. It is very simple and clean. The overall shape of the machine is obviously different from the previous Xiaoxin Air series. The B side is made of aluminum alloy. Instead of a fully covered glass cover, the edges and corners of the whole machine are more distinct. As for the screen, it uses a 13.3-inch 16:10 panel with a resolution of 2560 by 1600. This is one of the few 2K resolutions at the same price. One of the screen models. The nominal typical color gamut coverage can reach about 100sRGB. There is no doubt that it is a screen with the best paper parameters among similar models.
