A few of us at Steel Battalion Online OG Xbox community have put something together just in time for Insignia's beta launch. A relatively simple & cheap method to use modern gaming headsets with the OG Xbox Voice Chat Comm's.
No hard mods necessary just a couple adapters from Amazon and you will be Golden.
We've tested and with your modern headset you will get game audio, voice chat and microphone compatability all in the one headset like it should be.
Full Guide can be found here with links to required hardware.
