EMI RFI Noise Filter Cable Ring, Roctee 12 Pcs Ferrite Choke Snap On Noise Suppressor Cable Clip Electronic Ferrites Core for 3.5MM Diameter Wire (Black)

We bought these to install on our headphone cords because we were concerned about possible radiation while using the headphones and wanted to reduce it. The order was quickly filled and delivered. These are very easy to install. They just snap around the cord and stay in place if you order the correct diameter for your cord. We feel a lot better about using our headphones now. The very low price for added peace of mind was great!

Excellent purchase

Didn't work as expected. Could be on my part. Good quality easy installation.

it works good

This only work on a single AWG 16 or smaller wire

Didn't work for my application.. But ill keep them for other stuff

I had bought some led fog lights and when you turned them on the radio station would go out I put 2 of these on each bulb one on the positive wire and one on negative wire of each fog light and now the radio station comes in just like it did before adding the led fog lights

I had high hopes for the Roctee Ferrite Choke Noise Suppressor Clips, but unfortunately, they didn't meet my expectations. The pack of 12 is a good value, and they’re easy to snap on, but they didn't make much of a difference in reducing the static and interference I was experiencing on my audio cables.While the clips fit the 3.5mm diameter wire as advertised, they didn’t seem to suppress the noise significantly. After attaching several to my cables, I still had noticeable interference, especially with higher frequencies. Additionally, the plastic feels a bit flimsy; a couple of clips came loose after some light handling.If you're dealing with severe EMI or RFI issues, this product might not be effective enough. It could work for minor noise reduction, but in my experience, it didn’t provide the results I was hoping for.
