[Pack of 10 Ferrite Beads Clip - on Design for HDMI Cable USB Cable Noise EMI RFI Suppressor Ferrite Core Ferrite Ring (7MM)

I have this Zoom MultiStomp MS70-CDR that i got used that has this high pitch squeal that I can never fix, and I have nice isolated power supply units. Came across a comment on reddit that suggested these, and since they're cheap on Amazon, I gave it a try, and I'm telling you, IT WORKS! So I tried it on another pedal, IT WORKED AS WELL! So yeah, buy more of these to save you some grief! I ordered more since I hoard pedals. 😅🤣🤘🏾

I selected 20 pcs 5 sizes and I received 10 pcs 1 size. The description shows both. The associated image and color "20 pcs with 5 sizes suggest that was what I was going to get. "iSKUKA [Pack of 10] Ferrite Beads Clip - on Design for HDMI Cable USB Cable Noise EMI RFI Suppressor Ferrite Core Ferrite Ring (20pcs with 5 Sizes) I was able to make the 10 pcs one work for me.

Giving 4 stars even though it was better than I hoped. The thing is, I have a 3.5mm cord. I bought the 7mm beads. Best example is the photo in description that says "Applications". Shows a bead and a 12v (cigarette lighter) cord. If you look at the opening of the bead in that photo you see little teeth and a V shape. Long story short, the 7mm bead fit my 3.5mm cord. I thought I would wrap the cord through it twice to hold it in place. As if two cords were running through it. Turned out that that wouldn't work. One pass and those little teeth bite down into the cord holding the bead in place. So... 7mm is a great fit for my 3.5mm cord. Not sure if 7mm would work well on a 7mm cord. The teeth might bite down too hard. If I were to need/buy another. I would up-size to double or near double the diameter of my cord. Now hopefully it cuts out what little interference I have in the audio on my dash cam. Also, seems to be made well. The little latch clips seem strong and appear to be of a grade that shouldn't break easily as applied.

I am an avid Ham Radio operator. There is always stray RFI in the radio room or in our operations vehicles. I used these Ferrite Beads on an especially RFI prone project. They worked wonderfully!! Caution: Be sure you are buying the right size for your specific project.

Completely eliminated the radio noise in my truck caused by installing aftermarket led headlights. Great product very affordable and super easy to use no tools nessecary

The description states that this fits USB and HDMI cables. This did not fit either of the two. This ferrite core fits around cables such as iPhone charging cables and a small selection of skinnier/slimmer USB cables.

I bought these to filter RFI getting into USB cables. They worked for me

Not clearing up static problem as I hoped it would.

Funny enough I have yet to clip one on a HDMI cable, I purchased these for a usb audio cord to further help isolate noise. The entire pack is going to find their way to all of my devices. I'm actually quite surprised on the difference attaching on of these to your cords can make. Audio clicks and clacks vanish, Video quality improves. The Beads come packaged in a clear plastic case which is a nice touch. The beads can be a bit finicky to open, getting under the little plastic tabs, but they've all clipped back nice and secure. All and all very impressed.

Exactly as ordered. Would recommend to others.

Good

Pas vu beaucoup de différence pour ma perte de signal radio

When Ever I stood up From my Computer chair I would get an EMI Here is an article/paragraph I pulled to explain it It turns out that our gas lift office chairs are generating an EMI (electromagnetic interference) spike when they move up or down when we get up or sit down and that action is picked up on the video cables, causing a loss of sync and making them turn off and on. I had noticed that the screens would turn off and on when I got up but I thought it was just a coincidence, but if someone told me that merely getting up or sitting down on my chair could affect my monitors, I would call them crazy. My mind is blown because that is literally what is happening. This Product Stopped it in its tracks, I got the 7mm as it was a perfect fit for my thick Displayport/HDMI Cable Now I can save $700 bucks on a new computer chair which was the path I was on. Solved for $15 dollars :)
