Can you solve Headset to PC audio splitting without using that adapter?

[lemoniac109]

I have a headset with only one 3.5 mm 4-pole jack and I have speakers with only one 3.5 mm headset only jack(no mic). I want to use that mic with those speakers but only headset audio comes out,the mic isn't working...I want to solve that if possible

So, you have headset (mostly output-only device, with microphone for SKype and/or phone calls), with male 3.5mm connector.
YOu also have speakers (output-only device), with another male 3.5mm connector.

Is this correct? Do you want to be able to hear headset' microphone over speakers?
And what is "that adapter"?

If i read your question right your headset and speakers are separate, so try this split cable. It (may) pick up just the mic from the headset and will take the speakers and combine the 2 going into a port if it allows taking both headset/mic on same port. Now if you want to take 1 plug and make them two... then do the opposite.
