2 QC15 comes standard with two audio cables, one is ordinary, and the other is dedicated to Apple. If you use Apple products, you can control the volume, music selection, pause and other functions by replacing it with the one with a controller, and you can also control answering and hanging up when you connect to the iphone. The specific operation is the same as that of the Apple headset (for example, the answer key is double-clicked, and triple-clicked is the next or previous song)
