These are both a 50 x logitech g . Doesnt say refurbished why is it so much cheaper

im using the astro a50 lightspeed wireless + basestation (M/N A00186 / M/N A00194). The one with only usb c ports on the dock.

I cannot under any condition use the headphones without connecting via bluetooth. It will show and say "Headphones (4- A50 Game)" yet I cannot hear anything. This is with the power connected to an outlet with their usbc power cable and then the usb A to C connected from a usb 3.0 port on my pc to the PC port on the dock.
I can connect through bluetooth, but the bluetooth has an issue where it struggles with pausing audio or multiple audio playing through my pc. Basically I'll start playing something (spotify, youtube, etc) and it'll play 2-3 seconds before giving up. Then I have to try replaying the song? I don't get it. I did firmware update, uninstalling and reinstalling drivers, factory reset, the thingy of holding game + playsync whle on the dock until it flashes. Set as default device in control panel, etc etc

Do these headphones support connection without use of bluetooth? All phrasing in guides is vague on this. If so what am I doing wrong? Is it a dolby atmos windows 10 issue? I just got the headphones

Big fan of the astro series headsets. A50 gen 4 was maybe a bit of a disappointment for me. But a good headset nonetheless. Obviously the next logical step was the gen 5. My question is why cant I balance the game and chat audio with the game and voice buttons on the side of my gen 5s? The normal gen a50 gen 5. Not the a50x.
