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.

Helped massively with the radio reception after the rear dashcam knobble it. No interference and seems to have helped with the radio signal - seems clearer and stronger than even before the rear cam was fitted.

Electrics issue in a terraced house meant my neighbours were able to impact my rework. These worked a charm.

good

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.

Good value , does the job .

Fitted a new car play system with DAB Radio and the radio signal was cutting out when Dashcam was switched on and plugged into car lighter port. Fitted these today 1 on Front Cam wire, on 2nd wire for rear Dashcam and on the end of main power lead by the car lighter connection itself. Radio signal is now perfect and picking up channels that were not accessible for me where I live. Brilliant little product and saved me loads of money hardwiring/buying a more expensive Dashcam. ⭐️⭐️⭐️⭐️⭐️👍😀

These ferrite rings have made a massive difference to the reception and picture on my TV. Even though I have a decent set, I almost changed it, but now I have a perfect picture all the time. Brilliant 😍

They work great!! My pet ferrite even stayed away.

Sono ottimi, fanno bene il loro lavoro. Solo un appunto, controllate bene la misura dei cavi
