If you have a Woojer Strap 3, please click here.
The Woojer Strap Edge needs either a 3.5mm audio jack or a Bluetooth connection as its input. Headphones are usually connected via the Woojer Strap Edge's audio output jack. However, when using USB headphones on a PC, you'll need to set up audio mirroring so that both the headphones and the Woojer Strap Edge will work simultaneously.
Please refer to this article for setting up audio mirroring on your PC using OBS, or refer to this article for setting up audio mirroring on your PC using VoiceMeeter Banana.
