COMMON GROUND - HEADSETSA normal aviation headphone jack has two connections on it: .普通的耳机的插头有两个连接点：＂the tip is the active and the sleeve is ground or return＂这句话怎么理解？＂尖端是活动的，然后两边由地面返回？＂这样理解非常别扭．
The tip connects to a wire that goes to the positive (+) and the sleeve connects to a wire that goes to the negative (-) terminal.一条线连接正极，另外一条连接负极．
What we are looking for is to have both negative (-) terminals shunt together. Usually there is a solder joint in the plug where ground wire from the plug splits into separate wires that are connected to the negative terminals of the coils.
我们现在要找的是要能将两个负极焊接在一起的．在连接俩条负极的地线的插头上通常有一个焊点
Bold lines indicate common return of both left and right channels.粗线部分显示的就是左／右线路的回路
The most important thing to note is that the return current from the left and right channels of the headphone gets joined together.
最重要的一点是：左／右线路的回路有一个连接点．
