New Xbox Stereo Headset wiring diagram

Hi

I want to replace the Xbox stereo headset 3.5mm jack but need some assistance with the wiring.

The headset has a green sleeve around the wires and the wiring is different from the previous headset with a black sleeve

In the sleeve there is a green wire, a red wire, a greyish wire with copper wounded around it and a blue-striped copper wire.

Unfortunately I can not see the connection point on the existing jack as it is encased in a resin.

I am not sure as to which wires or combination of wires goes where on the new jack. All wires in online tutorials or diagrams is of diferent colour.

Thank you.
