The audio on my pc38x is not working
One day I just plugged in my Pc38x and they stopped working. I tested the mic and it works, I've tried changing the cord multiple times and have adjusted the volume disk, none of this has changed my situation. I've tested the headphones on my PC, switch, and PS5 and the audio doesn't work there either.

People think higher impedance heaphones need more power to sound as loud as lower impedance ones, but that's completely wrong, they just need more voltage but less current. The thing is that most solid state amps (the ones you can find on embedded IC in every PC/smartphone/tablet/whatever) are good providing current but struggle to output high voltages; that's why the higher the impedance load, the lower the power they output. But the only spec that determines the power needed by some headphones to output sound to a given volume is the sensitivity.
You can check exactly how much power (voltage and current) does any headphones need here: http://www.digizoid.com/headphones-power.html. BTW, most companies list the sensitivity as dB/mW (which is absolute) while some others use dB/mV (which is relative to the headphones' impedance). If not said otherwhise, consider the sensitivity is listed as dB/mW.
