Cable replacement - Headset to PC

Question

I am looking for a cable, and I can't find it at all at any store.
The cable has : one pin going to the headset(on the right). The other two are the normal Mic(middle) and Out for audio(left) of a PC. And a microphone in the bottom of the picutre.
Do you know what this is called ? Or any suggestion for a workaround ?

Answer 1

If you can't find such a cable you can replace it with two:

• mic-in-cable
• splitter

Those products are just an example.

As a bonus without the splitter you can use this as a headset with your mobile phone.
