Audio splitter not working

[Smino]

So I got this audio spliter for my turtle beach Recon 150s and for a couple days it worked but now my microphone is picking up the output audio that my headset is receiving.

This is the splitter I have:https://www.gearbest.com/cables-ada...MIssvLgof-1gIVEIZpCh3jPwHvEAQYBSABEgKpoPD_BwE
