Review on Efficient Noise Filtering: 20 Pcs Snap on Ferrite Core Cord Ring for Various Cable Diameters, Black by Rey Hossain

Revainrating 1 out of 5

Didn't work for me when I installed the audio/video system in the car.

. Everything I read on the internet related to the grounding problem (which was revealed by touching my computer case as that would lessen the problem) and several people have stated that a ferrite core on the USB cable will solve the problem. Needless to say, they do nothing at all. I've tried several USB cables, a core attached to each end, I've even tried putting one on the headphone cable itself. In general, nothing has changed and glitches can still be heard.

Pros
  • . Annual Testing Period
Cons
