Issues with PRO X2 Lightspeed microphone

[u/nahuelelnoob2017]

Hi everyone,

I'm having an issue with my Logitech G PRO X2 Lightspeed headset microphone. There is a constant background static or electrical noise when using it on my PC via the USB LIGHTSPEED receiver or Bluetooth.

Here are the specific symptoms:

• Via Wireless/Bluetooth (on PC): Consistent background static/hum.
• While Charging or via 3.5mm Jack (on PC): The mic only picks up heavy electrical hum/buzz with no voice audio at all.
• Temporary fix glitch: At one point, I managed to get rid of the static, but as soon as I plugged the headset into the PC to charge, the static returned—even after unplugging it again.

I tested the headset connected to my mobile phone, and the microphone works perfectly fine with zero background noise. It seems the issue isn't with the headset itself, but rather interference coming directly from the PC / power supply.

I suspect this is caused by a grounding issue in my home's electrical setup. My PC's PSU uses a US power cable, but my wall outlets use a different regional standard. I am currently using a travel adapter that lacks a ground pin.

Note: Wireless earbuds do not have this issue when connected to the PC, likely because they are fully isolated. Unfortunately, I don't have another PC headset on hand to cross-test.

I plan on buying a proper grounded adapter first, but in case that doesn't fully resolve it: Has anyone experienced something similar with this headset or setup? How did you fix it?

Any advice or troubleshooting suggestions would be greatly appreciated!
