My Phone is Oukitel k-4000 Pro. I bought a headphone. But, then the problem came out. My phone does not support headphone output, just like in the picture. My phone's headphone jack is like everyone else, just a flat ledge.In my headset, There is an additional usb input.That's why I can not put my headphone on the phone. Would I break the usb output? Or is there another way to do that?
