Question about G433 - 137745

Is it possible to order the Pc 4pin aux cable? I tried the mobile cable as an alternative, as the other one is broken, but then no sound is recorded from the gooseneck microphone, only via the small one on the cable. I would be happy if someone knew where I could get one of these, as otherwise I will only be able to use it as a normal headset instead of a headphones. Greetings and thanks already.
