10 Pcs Ferrite Ring Core Black Clip-on Ferrite Core EMI Noise Suppressor Cable clip with 3.5mm inner diameter for USB Cords, Audio and Video Cable Power Cord

Nextbase hardwire dash cam kit, rear view camera completely wiped out Dab radio in my S3. Only fitted two of these on the rear camera wire, one close to the front and one close to rear camera where the wire came out of the trim. Result - full dab working great again. Added a few more along the wire (which runs in the trim above the doors) for good measure and it's perfect. They are a snug fit (which is a good thing for reducing noise/interference) and as other's have said they can be a little difficult to snap shut. But persevere as it's just a bit of a nack. Only down side was that I was only supplied 7 in the packet where there should have been 10. Didn't want to mark the review down of the actual product as I would recommend these for fixing the same problem I had. And for £6 jobs a good'n.

Good price, good product, came quickly, delivered properly through letter box with email notification. Robust clips on strong plastic housing open up easily to reveal two long hemispherical ferrite magnets inside housing, clips for 3.5 mm cable size shut very securely and the whole thing fits nicely on cables.

These work if used properly

This did help some of my Wi-Fi problems, and still left with a few. Would recommend if you are looking to resolve a Wi-Fi issue.

Good quality, helps with the noise, great value

Wrong size to close the clasps, I don't think they took the thickness of the lead into account but managed to fit them by using a zip tie to close them. It did make a difference (I was getting a scratching sound through my PC speakers whenever I moved the mouse), but lowered the sound rather than completely eliminate it.

Brilliant did the job perfectly. Power cables and ethernet.... dont ask but they worked

Good quality fit nice and tight. Would deal with again 👍🏻

Werk perfect

Hace su función, sobretodo con el suministro eléctrico de los aires acondicionados inverter. ( comprobado con medidor de emisiones electromagnéticas). 2 de 13mm de interior por cada compresor inverter sirven para cancelar las emisiones de esos equipos.

Verwendung zur Mantelwellen Unterdrückung auf einer RG213 Koax Leitung. Die Ferrite passen gut auf die Leitung, ohne zu rutschen, oder die Leitung zu beschädigen. Die Unterdrückung ist auf Kurzwelle (80m..20m mit 100W) deutlich zu bemerken. Ergo eine gute Wahl!

Perfect, thanks!

Semble bien diminuer le bruit de parasite
