After knowing the location and function of the AUX interface, we have to spend a few dollars to buy cables. The quality varies. The best so-called Akihabara audio cable is 15 yuan at most, and the average one is 3 or 5 yuan, which is not much different. .
Conversion plug
The single-to-single 3.5MM audio cable is the same as the one on your computer headset, with single ends at both ends. Connect one end to the AUX interface and the other to your mobile phone! If your mobile phone cannot be plugged in at the other end. oh! Then buy another conversion plug, which is called a 2.5 to 3.5MM conversion plug in jargon. It costs up to 5 yuan.
In addition, there are also single-strand cables on the market, with one end 3.5MM and one end 2.5MM, so there is no need to transfer.
