I found placing the loop in the middle for lows was a good place, with the highs clip at each end close to the connection. Review: Good selection of sizes and yes they do seem to have a positive effect! - I was having a bit of RF or EMI interference issues while recording in my new space and thought I'd give these a shot as they are much cheaper than a power conditioner and yes they do seem to be reducing my RF/EMI interference issues and even seem to help a little with some background hiss on my audio a bit, but I'm very picky about my audio and I am listening to it through professional studio monitoring headphones, so people other than audio professionals and proper audiophiles may not notice any great difference, but they certainly seem to have worked for me. :) ## Features - ELIMINATE ELECTRONIC INTERFERENCE INSTANTLY: Stop annoying buzzing, static, and signal disruption in your audio/video equipment with our professional-grade ferrite cores - no more frustrating interruptions during important calls or entertainment - UNIVERSAL COMPATIBILITY SOLUTION: Complete 20-piece kit with 5 different sizes (3.5mm, 5mm, 7mm, 9mm, 13mm inner diameter) fits virtually all cables - USB chargers, HDMI, audio cables, power cords, and computer peripherals without guesswork - WELL MADE AND HIGH QUALITY: The ferrite choke made of plastic housing and ferrite core, with inner self-adaption clip can mount on cables tightly and work for a super long time. - EFFORTLESS 10-SECOND INSTALLATION: Simply snap-on design requires no tools, cutting, or technical expertise - attach anywhere along your cable length for immediate noise reduction and cleaner performance - SIZE: 3.5mm: outer dimension-25mm x 13mm; 5mm: outer dimension-25mm x 13mm; 7mm: outer dimension-30mm x 17mm; 9mm: outer dimension-35mm x 20mm; 13mm: outer dimension-36mm x 24mm. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MG8GQ1F | | Are Batteries Included | No | | Best Sellers Rank | 8,519 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 8 in Ferrite Cores | | Brand | Dreamtop | | Colour | Black | | Customer Reviews | 4.3 4.3 out of 5 stars (1,564) | | Date First Available | 2 Nov. 2016 | | Guaranteed software updates until | unknown | | Item Weight | 290 g | | Item model number | DMT532-UK | | Manufacturer | Dreamtop | | Product Dimensions | 38.1 x 27.94 x 5.59 cm; 290 g | | Series | Ferrite Core | ## Images ![Dreamtop Ferrite Core Noise Suppressor Beads - 20 Pack EMI RFI Filter Clips for USB Audio Video Cables, Multi-Size (3.5-13mm) Cable Management Solution for Electronics Interference Reduction - Image 1](https://m.media-amazon.com/images/I/71EJJsfLq4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does the job for audio cables. *by B***R on 17 March 2026* Pretty good products, they reduced both the low end hum (with the loop trick) and high end hiss (with the single wire through).

It was part of a 'housekeeping' project to tidy up the rats nest of cables behind the TV, separating switch mode supplies into a dedicated distribution block and physically distancing them from speaker cables etc. They are easy to use, just select the appropriate size and they just clip on. A cheap solution that will reduce electrical noise. My hi-fi amplifier was the only device that I didn't fit a ferrite bead to, as it has its own mains conditioning, that was just plugged into its own mains socket. ## Frequently Bought Together - Dreamtop 20Pcs Ferrite Core Ferrite Choke Ferrite Clip-on Black Ferrite Ring Core RFI EMI Noise Suppressor Cable Clip with 3.5mm 5mm 7mm 9mm 13mm Inner Diameter for USB/Audio/Video Cable Power Cord - CS947 Tacima 6 Way Mains Conditioner with Surge Protection - HUAREW Black Clip-on Ferrite Ring Core Ferrite Choke RFI EMI Noise Suppressor Cable Clip for 3.5mm 5mm 7mm 9mm 13mm Diameter Cable(5 Values 28 PcsοΌ‰ --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/47957569-dreamtop-ferrite-core-noise-suppressor-beads-20-pack-emi-rfi](https://www.desertcart.jp/products/47957569-dreamtop-ferrite-core-noise-suppressor-beads-20-pack-emi-rfi) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-13*
