🔒 Stardrift 10-Pack 11mm Black Snap-On Ferrite Core Bead Choke Ring Cord RFI EMI Noise Suppressor Filter - Ideal for HDMI DVI VGA Cable Review

These ferrite core filters are not easy to open initially as the locking tabs are shipped locked. It takes a tiny screwdriver to pry one of these off and use your fingernail to hold it open exposing the other side. Once placed, click to close.

I have a police handheld scanner that requires a line filter when plugged into my car's USB port due to signal loss due to noise. Cables with built-in ferrite cores are either expensive or bulky. I bought these to use my existing cable. I didn't want a set of 10 but the price was so low I bought them. DVD recorder, FPV glasses, drone and power supply units for my Raspberry Pi. Approx. 80 cents each additional protection against possible noise.

I've been hearing a lot of static/humming noise from my PC speakers, especially when using 3D applications. I found that my onboard audio was picking up interference from my graphics card, so the static noise tripled when running something graphics-intensive. Adding it to my audio cable reduced the noise drastically. It didn't completely eliminate the hiss (I really have to crank the volume up to still hear a slight buzz), but there's no buzz from 0-70% of the master volume. I usually listen…

A little background: I'm a radio amateur who often turns on 35-100 watts from my office. This sends enough interfering radio frequencies into adjacent computer cables that without the ferrite beads on either end of the links, the Caps Lock LED will illuminate and various peripherals will shut down or jam during transmission. (My 27-inch aluminum iMac is very well insulated on its own.) I ordered these ferrite rings because they were advertised for USB cables. I had to think more about their 3mm
