Product reviews3.5mm Jack Ground Loop Isolator Remove Unwanted Hum From Audio Equipment

Does not work

I have a really annoying mains hum when I connect my laptop to a set of powered speakers. I use the set up for Zoom meetings. When I unplug the laptop and run in batteries there is no hum. This device claims to eliminate mains hum for exactly this scenario. However there is absolutely no difference if I use the device or plug the speakers directly into the laptop. Waste of money unfortunately. Also if I move the attached cables when it is plugged in I get crackling noises indicating that something is not quite right in the wiring. Read full review...
