If we had music on low volume, we could also hear the muffled sounds of talk/news radio. Not quite loud enough to hear the words, but enough to bother me, like hearing a neighbor's TV on through an apartment wall. These ferrite cores fixed our problem. It took two on each end of the speaker wires, and for extra protection I put one on the speaker power cable too. I also moved our speakers a couple feet closer to our computer table and coiled up the extra wire with a zip tie to reduce the length of "antenna" the speaker wire was creating. Now I can only hear the radio signal if I put my ear directly on the speaker with nothing playing. I feel like the sound quality of music and movies has also improved somewhat? Review: Auto LED light bar head unit static - LED light was making static in the head unit after installing a front facing camera. I used these on the light power wires very close to the light bar. The static is completely gone. The quality is good and none were broken. I am very satisfied with the product and results. ## Features - Package included: 20 pieces ferrite cable clips (with 5 different size) - 3 mm: outer dimension-25 mm x 13 mm; 5 mm: outer dimension-25 mm x 13 mm; 7 mm: outer dimension-30 mm x 17 mm; 9 mm: outer dimension-35 mm x 20 mm; 13mm: outer dimension-36 mm x 24 mm - Fits for cord with 3 mm, 5 mm, 7 mm, 9 mm and 13 mm inner diameter - Reduce electro-magnetic interference and improve signal integrity - Color: black ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.3 out of 5 stars 644 Reviews | ## Images ![20 Pcs Snap on Ferrite Core Cord Ring RFI EMI Noise Filter Suppressor Cable Clip for 3.5mm/5mm/7mm/9mm/13mm Diameter Cable, Black - Image 1](https://m.media-amazon.com/images/I/51gXjI0NsrL.jpg) ![20 Pcs Snap on Ferrite Core Cord Ring RFI EMI Noise Filter Suppressor Cable Clip for 3.5mm/5mm/7mm/9mm/13mm Diameter Cable, Black - Image 2](https://m.media-amazon.com/images/I/41FBPpe3KBL.jpg) ![20 Pcs Snap on Ferrite Core Cord Ring RFI EMI Noise Filter Suppressor Cable Clip for 3.5mm/5mm/7mm/9mm/13mm Diameter Cable, Black - Image 3](https://m.media-amazon.com/images/I/51hkjaTyTyL.jpg) ![20 Pcs Snap on Ferrite Core Cord Ring RFI EMI Noise Filter Suppressor Cable Clip for 3.5mm/5mm/7mm/9mm/13mm Diameter Cable, Black - Image 4](https://m.media-amazon.com/images/I/51RNzcP5CkL.jpg) ![20 Pcs Snap on Ferrite Core Cord Ring RFI EMI Noise Filter Suppressor Cable Clip for 3.5mm/5mm/7mm/9mm/13mm Diameter Cable, Black - Image 5](https://m.media-amazon.com/images/I/41hvIPxCmwL.jpg) ## Questions & Answers **Q: Could these work for a 3.5mm double coil wire?** A: These cores come in various sizes, that you need 3.5 mm is accommodated in a 1.5 mm cable at least up to 3.5 mm maximum, and if it does not work, you can use the core of 5 mm, which fits into a 3.5 mm cable at least up to 5 mm and I think that the cable you have should fit well in one of those two cores. **Q: what frequencies do these absorb** A: that depends on the length of cable they are being used on. It's the cables that act as antennas, both radiating and receiving signals. It may take multiple units on your cables to reduce/eliminate the bothersome signals. **Q: Will these filter out a radio station leaking into my audio** A: It depends on the strength and the proximity of the transmitting station. Under most conditions, you may be able to minimize or eliminate incoming radio frequency interference by clamping these onto your speaker leads. It may take more than one if the signal is very strong. **Q: Could these work for a 3.5 mm double coil wire?** A: Should work fine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Helped computer speakers *by F***S on January 18, 2023* Our computer speakers were picking up radio signals in the background.
