3.5mm headphone jack structure

The 3.5 mm plug can be generally divided into three cores and two cores. The two core plugs are generally used for microphones, and the three core plugs are generally used for stereo sound headphones (active speakers). Now there are very few two-pin plugs, so the microphone also uses a three-pin plug.

 The problem arises in the number of links at the socket of the headphone jack (that is, there are several loops and one turn around the socket). In the past, the number of headphone jacks is 2, and the new headphone starts to use 3 links, which can improve the headphone. Expressiveness, the incompatibility of the headphone jack should appear here, so be sure to pay attention to these issues when buying headphones. To buy a headset that fits your phone's headphone jack, you can look at the links in your phone's headphone jack that come standard with the headset and then go shopping.
