I ordered a 3m 3.5mm, OFC copper microphone extension cable to plug directly into my usb soundcard. This is to replace my current setup of a 1m usb extension cable (with usb sound card in) and 2x 1m microphone cables. The current setup, while a bit silly, does pretty well. This new cable, though, introduces a ton of noise while using the microphone. I'm just wondering what causes this.
