-Clip on ferrite bead cable can be used on all kinds of wire cords such as: Power Cord, Audio Cables, Data Cable, USB Cables.
-It helps improving the electromagnetic field and signal quality around the cable, avoiding outside interference.
-It won't cause distortion of the transmitted signal and won't affect your audio, video and picture quality.
Note:
Please install them in place near the interference source. (Near the import and export of shielding case as much as possible.) If a cable has equipment that needs to be protected on both sides, install one at each end.

Cured some of my EMI problem.

I have a decent headphone amp and dac hooked up to wiim pro but everything is connected to a surge protector which a microwave and lights and a coffee machine is hooked up to as well, after putting the ferrites in different places and looped some of the cables and eventually I was able to get all the noise out of it and everything is crystal clear now

Using these ferrite cores on wires going in and out of my vacuum tube guitar amp really helped reduce background RF interference noise and hiss. Quite happy with this product.

I have one of these on most cables in my ham radio station. They really helps to eliminate computer and "wall wart" hash on receive and transmit RF getting into computer speakers and other audio equipment. Always put as many turns of cable as you can fit into the ring, as this is much more effective than just clamping it onto the cable..

Inductance is proportional to turns-squared so 1-turn (just clamping it over a wire pair) is 0.25 uH, 2-turns (if two will fit) is '2-squared' = 4 x 0.25uH = 1 uH, 3-turns would be '3-squared' = 9 x 0.25 = 2.25uH, etc. You can also add several of these in a row to increase RF filtering. Common mode rejection requires that both wires go through the ferrite core in the same direction (typical use). Differential mode noise rejection where noise is entering by just one wire requires that both wires go through the core in opposite directions.

Perfect size for multiple winding turns of small diameter cables and wires. Very effective for filtering noise in my amateur radio gear.

didn’t do anything to help with any electrical interference. Seller is good though. Easy purchase and return.

So far so good, the larger diameter center hole work with cables that you want multiple passes (attenuation is the ^2 of the number of times the cable goes through if I'm remembering it correctly )
