De acordo com os documentos de suporte da Turtle Beach, é necessário fazer o seguinte para usar o fone de ouvido no modo com fio conectado a um PC.
1) Power on the PX3 headset.
2) Insert the USB Mini-B end of cable into the headset and the USB Standard-A end of the cable into your computer.
3) Double-press the Power button on the headset to enter Wired Mode. (When you double-press, be sure to press the button firmly, but not too quickly; if the double-press is done too quickly or too slowly, your computer will only recognize your headset as the PX3 Charger.) When successful, a double tone will sound and the LED on the headset will change to solid RED.
4) Go into your computer's sound settings and make sure "PX3 Headset" is set as your playback or output device.
