Connect headset to laptop? - 2

I got a headset for Christmas. Since I only have one jack connection on my laptop, I ordered such a jack adapter.

Now I have connected the headset to the laptop via this. However, it seems to me that the microphone on the headset is still not working. In the Windows device settings, the input device is Laptop Micro.

Have I forgotten anything? Because I don't know what to do now.

Did you mix up the jack connections? Pink for the microphone and green for your headphones?
