Headset is not recognized?

Hi lately just bought me a simple headset only my laptop has only one socket and my headset two when I put the microphone in the jack did not recognize the laptop. What is this and what adapter should I take?

You need, for example This one, if I understand your question correctly:

The connection to your laptop is a 2in1 connection. So that's a headphone and microphone jack in one. Google just after "3.5mm jack 2in1 adapter" and take one of you zuspricht.

Here's an example:
