The attached images show the measured impedance of a short piece of wire (using a Digilent AD3) when enclosed in various combinations of beads: one 3.5mm bead; two 13mm beads; one 13mm bead.

A very generous bag of magnets of various sizes. Traditionally, this was found on a lot of electrical equipment primarily from the earlier 90s / 2000s. Historically we used to this mask interference caused by low quality cables, generally ones without any shielding.I tested this on my DIY speaker build, which has some static interference when the AUX is not connected to my device which is grounded.I have tried various points of the device and unfortunately, found it made no difference.The plastic clips used to hold it around the cable feel a little cheap but the magnet material feels decent.I don’t believe this will make any difference to modern products but might be useful for old devices.

These little ferrite clips have made a noticeable difference in my home audio setup. I was experiencing some annoying buzzing and interference, especially near my computer. After attaching these clips to various cables, the noise was significantly reduced. They're easy to snap on and stay securely in place. The variety of sizes means they can fit most cables I own. It's a simple, affordable solution that's made a big improvement in my listening experience.

If you've ever had interference issues you'll understand why these little ferrite ring cores are essential. If like me you have a spaghetti of cables all working within proximity of each other adding these to ensure your signals remain crisp and clean saves a massive headache to eliminate unwanted noise.The order arrived on time, a good selection of sizes, kit consists of five different sizes. 70 pcs in total.At the time of this review, £25.99 making each one +/- 37 pence each.

This provides a great selection of ferrite cores to reduce RFI. Note that you can gain efficiency in RFI reduction by looping a cable through the same core multiple times. It is work picking a larger core if you can get multiple passes through the same core. This is more efficient that using multiple cores. Though you can do both for even more RFI blocking power.Price as reviewed $27.99. 70Pcs Ferrites Clip-on Ferrite Ring Core RFI EMI Noise Suppressor Cable Clip for 3.5mm/ 5mm/ 7mm/ 9mm/ 13mm Inner Diameter Tvs,Speakers,Radio,Audio Equipment Noise Suppressor Video Cable Power Cord

The different sizes in this set are useful for all kinds of electronics to help shield interference. They clip on nicely and the outer shell is a good plastic. It is nice to have the variety so I can loop a cable if I choose, or use them straight, and I can swap them depending on how well it works.
