I bought my first pair of these 4, maybe 5? years ago. I only use them to watch TV and really like them. After a couple of years the volume knob started not working properly. I hardly ever use it as I set the volume once and for most TV it is fine. Once in a rare while I will adjust them a little. What happened is that the adjustment would cause static or cutting out in one ear when turned. I figured I had them for 2 or 3 years, I would just replace them. I did and all is OK for a couple of new years with the new set. But just this week they started doing the same thing.

Is this something common with these? Seems like a loose connection or something. I searched and saw a thread here about another brand doing something similar and the suggestion was to "clean" them. Does that make any sense?

It is something absolutely common with all contacts, especially rotating ones like volume potentiometers, the more if you use them once in a while. To clean it try first of all to rotate it rapidly from zero to full scale a few times.
Best thing to do, of course, is to spray inside some contact cleaner.
