Is it possible to set Phantom Golds to standard speakers on my laptop?

[Limtre]

I'm sorry if there is another thread or guide on this, but I couldn't find it.

I've just bought two Phantom Gold's and while working I'm listening on different podcasts, radio - things that are not on Spark or other apps on my laptop (streaming through websites) and I would prefer to do this on the Phantoms.

I am wondering if there is a way to set my Golds as standard speaker on the computer like I do with my headset through WiFi or Bluetooth, or if it's possible to get them up as a casting-device (like chromecast)?

My system:
Laptop with Windows 10 Home connected to the router with WiFi
Dialog, firmware 1.14.1.3, connected to the router with cable
2x Phantom Golds, firmware 1.14.1.13 connected to the Dialog with PLC 

If connecting the Golds with Ethernet-cable to the router would help on the situation I'm willing to do that.
