Back in the day
I used to do desktop support and had to go visit one of our extremely less than technical users. We supported damn near everything that had a wire in it too.
On this particular day she was complaining about a hum in her telephone headset. This was was a hard wired Plantronics to an Avaya IP phone. The hum was only in the headset. Not the handset or speaker phone. She would say the hum was there, take the headset off and hand it to me and I couldn't hear anything.
Finally, I noticed that she had one of those warming pads that you put in the chair. I had her stand up and she immediately said the hum was gone. I unplugged the pad (it was strapped to the chair and I didn't want to fuck with it) and she confirmed the hum was gone.
She got a wireless headset that after that.
