Review on 🔒 X.shine 10-Pack Snap on Ferrite Core Bead Choke Ring Cord RFI EMI Noise Suppressor Filter for USB/Audio/Video Cable Power Cord - Black (7mm Inner Diameter) by David Angelboy

These things are like magic. We have an audio interface that allows us to play music from our desktop computer through our church audio mixer. Despite the fact that the interface is very good hardware, we always felt a little noise on the channel. After reading the article, I learned that since the audio interface is powered by the same USB cable that carries audio, the power flowing through that cable can cause interference. These little magic wraps kind of take that noise away. It was so easy to plug one of them into the USB cable next to where it connects to the computer. It's like magic and insanely cheap!
