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

Good quality, helps with the noise, great value

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 look great if you have any kind of ribbon cable, especially speaker cables then be good. I ordered them by mistake so never tested them

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

Nicely made only wanted small,for a ham recive loop,good time on delivery and well wrapped. Good job. Db u.k

I have used these on USB caples from sdrs such as hackrf one. They do the job.

These seem to be well made but, they are way too small to fit USB cables, which they are advertised to do. I bought the 3.5mm type.

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.

Ho preso questo set di anelli di ferrite per ridurre un po’ di interferenze su alcuni cavi audio e USB e devo dire che funzionano bene. La clip è solida, si chiude senza sforzo e non dà l’impressione di rompersi dopo un paio di utilizzi. Una volta agganciati rimangono stabili e non scivolano lungo il cavo. L’effetto sulla pulizia del segnale si nota: su un paio di cavi lunghi avevo un leggero ronzio e, dopo averli montati, la situazione è migliorata sensibilmente. Per questo lato tecnico, promossi. L’unica cosa a cui prestare attenzione sono le dimensioni interne: sulla carta la misura dichiarata dovrebbe permettere di inserirli comodamente, ma nella pratica li ho trovati leggermente più piccoli del previsto. Se il cavo è un po’ spesso rischia di non entrare bene, quindi conviene verificare prima. Per il prezzo e per la qualità complessiva, comunque, li ritengo un buon acquisto. Se avete cavi sottili o standard, fanno esattamente ciò che devono fare.

Très très bien

For what you pay for this, can't beat it. Using them around the house on speaker and USB cables to prevent injection of my HF tranciever and they work great. It's probably not mix31 but it works well enough for the cables I use it on. Very happy!

Hab ein paar ältere Aktiv Lautsprecher an meinem PC von Logitech an meinem PC. Leider haben die von Haus aus schon gewisses Eigenbrummen. Vermutlich ist da intern irgendwas schlecht geschirmt. Der RCA Ausgang am PC brummte bereits beim Hochfahren des Rechners. Der Klinken Ausgang machte das gleiche. Bessere Kabel gekauft, ohne irgendeine Verbesserung. Jetzt 2 der Feritte auf beiden Enden des Kabels drauf gemacht. Passen einwandfrei. Der Brumm ist erheblich leiser geworden. Machen also genau das was ich gewünscht habe. Empfehlenswert.

Do what it should do. Easy to install
