These worked perfectly to reduce noise in my HF Ham radio. I put them on everything including a led lamp lighting my station and the noise floor dropped dramatically. I appreciate the different sizes and the amount for the price. My sole complaint is they can be hard to lock closed. Once done however, a one time thing, you have a quality choke.

I appreciate that there is a variety of sizes, and they are easy to put on. In my particular situation, it did not address the issue - a hum in a tube amp probably caused by a ground loop - but for very little effort, it was worth a try and certainly didn't make anything worse.

This works and it's very easy to use.For years my mechanical keyboard turned off or flickered whenever my box fan from across the room (on a different outlet) changed modes. It was driving me crazy! Eventually I asked AI what it might be and it recommended Ferrite Beads, so I tried this out and sure enough it solves the problem! I grouped all my usb dock cables into one bead, added one to both sides and now the connected devices are totally unaffected by fan mode changes and probably other things too.

I have 3 studio monitors (L,R,mono reference) and used 6 of these, 1 on each balanced XLR cable and 1 on each power cable. Prior to installing these, my cell phone would cause hissing/pop/general interference within 4-5ft of each speaker. Now, I can stick the phone right next to the tweeters and cones, and zero interference. This was my first solution to the problem as it is very inexpensive, and I'm so happy it worked.If anyone else has these issues, I highly recommend you give this a try as its very cheap, and worked 100% for my issues.

I'm giving these 4 stars because I know they work, and they seem like a quality product, but they didn't solve my issue. I was hearing a buzzing noise from my speakers (not a ground loop hum) when I scrolled my screen or moved my mouse. I tried many different things, including these ferrite rings, using one, and then a few, and even looping the USB cable through a larger one with one and two loops. Nothing made any difference. Balanced audio cable from my DAC to my amp solved the issue.
