@Junsred Your headset will work if you plug it into the audio jack on the tablet part of the Switch (use the 3.5mm plug).
This works both while you have the tablet docked and while it's separated from the dock. The plug is located right next to the vent on the top edge of the tablet. After my first generation VOID broke down on me a few days ago I noticed the Surround edition had the 3.5mm jack and opted for that one over the USB edition I previously had expressly for the purpose of using it with my Switch. :) Glad they work well with each other.
