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.

2 years of EMI pain from my (very good) Creative powered PC speakers resolved in a few minutes for a few quid. I arrange music for a variety of bands and the interference on playback was driving me insane. Be prepared to experiment with the placing of the cores on power, speaker and connection cables. Oh, and use a shielded connection cable - doesn't need to be one of the insanely expensive hifi ones as long as it's shielded. Your mileage may vary, but a great big easy win for me.

I purchased these to go on a cable for a Nextbase rear camera they where slightly to small but I used a cable. Tie to hold it on. I put one on the front cable by the camera and two by the rear camera My DAB reception was really bad kept dropping off. Since fitting all good

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.

Got a Vr headset recently that requires Lighthouses for tracking to work but in racing sims specifically the headset would constantly lose tracking and go in and out of Grey screen. Placing one of these on the headset’s cable close to the junction box fixed the issue. Couldn’t be happier….

Good value , does the job .

Really good item for getting rid of interference on dab radio add ons

I used 6 ferrite rings one on each input and output for the two cameras plus an extension lead. DAB signal improved considerably.

The ferrite core works as expected and fits well with the specified size.

Bon produit

Perfect, thanks!

Das Öffnen und Schließen funktioniert sauber, die Clips rasten fest ein und sitzen anschließend sicher am Kabel. Die Verarbeitung wirkt hochwertig und stabil. Besonders positiv: Die EMI‑Rauschunterdrückung zeigt sofort Wirkung. Störgeräusche an Lautsprechern, Monitoren oder USB‑Geräten wurden bei mir deutlich reduziert.

Für den Preis bekommt man ein zuverlässiges Entstör‑Set, das technisch überzeugt, vielseitig einsetzbar ist und Kabel sauber aufwertet. Klare Empfehlung.

Estas ferritas redondas son recomendadas para enviar la radiofrecuencia en los equipos de radio, pero también se usan para aislar otro tipo de equipos. Se nota el resultado una vez colocados.
