Hello there.

Have you acticated the microphone in Recording Devices? Right click on the Sound Speaker -> Select Recording Devices -> Select micriphone -> Right click and select as default device

If it doesn't work, then the Sennheiser need a custom adapter. You cannot use simply those startech.
You will need the original PCV05 or PCV07:

Oh, I see why.
Good catch, Natsukage.
The splitter you got is definitely the wrong kind of splitter.
