Review: Great set of Ferrite choke rings - Great set of Ferrite choke rings to fit every size of cable you are going to use in your home. A Must with how bad the UK mains power can be with Radio interference, power surges like when Fridge comes on or off causing a crack in sound from the speakers of your expensive Hi-Fi or TV. The use of Ferrite choke rings on your cables of sensitive electric equipment will help suppress or stop the mains power surges and Radio Interference which can be very bad if you live high up like on a hill or near a number of radio masts. These Coke rings come in a nice to use box and are easy to fit.
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. :)

### ⭐⭐⭐⭐⭐ Cheap, simple, effective in reducing electrical noise.
*by M***C on 19 January 2026*

I used these around the cable outputs of many switch mode power supplies and mains cables to reduce the amount of 'electrical noise' near to my hi-fi amplifier and other equipment. 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.
