USB wall outlets a source of noise in AC lines?


I've got a couple of these on the same mains circuit as my audio gear. I'm wondering if they generate any noise on the lines, since I guess they're just small switch-mode power supplies. If so, would they make the noise all the time, or only when something is plugged in?

Can't say as I'm hearing any noise or sound quality impact, but would appreciate any suggestions or thoughts.

I can hear when dimmer switched lights are on. I have dedicated mains runs from the breakers. If you can, try reduce all pollution. I’d get rid if them.
