Razer Kraken Pro V2 Echo Issue

Hello, I have been dealing with a very annoying issue. I bought a Razer Kraken Pro V2 3.5mm headset a few months ago, and discovered that people can hear what I hear so I spent months trying to fix it myself but to no avail, I will list what I have tried so far and I hope somebody who has experienced and solved this, can help me out.

• Mute microphone via the button on the cable to check sensitivity, but nope. Even when the microphone does not pick up external sounds like me talking, it picks up sounds on the computer e.g. music I am listening to.
• I found that it could be EM interference due to the splitter, so I bought a new one but it was still the same.
• Normally both connectors are plugged into the motherboard but I tried the front panel, even if it's backwards thinking, just to see if there's a faulty connection on my back I/O connectors, didn't work. (https://www.asus.com/us/ROG-Republic-Of-Gamers/ROG-STRIX-Z270E-GAMING/ )
• I bought a 3.5mm to USB 2.0 adapter to see if that would help by switching to digital I/O, but still didn't work.
• I've checked the "Listen to this device", "Set default" settings, but still didn't help.
• All drivers/ BIOS are updated.
• I've used different programs to ensure it's not just Discord's "Automatic Gain Control" spiking.

This is what I can remember off the top of my head as of now. I've tried adjusting the gain of the Microphone to try and mask the sounds that are transmitted, but sadly that also affects my own voice and thus people can't hear me well, which defeats the purpose of a mic. I've reached the end of my wits at this point, I'll be glad to provide further information if I missed anything. Thank you in advance.
