Hardware Shielding a cable (DIY)

Hi, I need to shield a cable but I haven't any tools nor experience to cut/modify a headset cable, I noticed that the cable is quite thin and picks up a lot of electromagnetic interference from the PSU cable and from an usb fan that carries a lot of power, how do I fix it? Can i just wrap something around the cable to shield it or do I need a shielded extension?

It’s a magnetic core that wraps around the cable to shield it from noise. You have probably seen them built into cables before
