This 3.5mm plug to plug cable is an ideal replacement for your existing headphone cable that includes a microphone and in-line controls. Perfect for adding a mic in-between your gaming console controllers, car stereo or portable speakers. The 3 pole 3.5mm stereo plug at one end plugs into your headphones and the other 3.5mm TRRS plugs into your device such as a gaming controller, smartphone or tablet. The in-line microphone allows you to make calls, and the switch buttons can answer or hang-up calls. You can play or pause your current music track and adjust the volume up and down.
