HUAREW Black Clip-on Ferrite Ring Core Ferrite Choke RFI EMI Noise Suppressor Cable Clip for 3.5mm 5mm 7mm 9mm 13mm Diameter Cable(5 Values 28 Pcs）

Very pleased with the good quality and large selection of filters - covers every option.

I grew tired of ordering individual chokes so ordered this box. Now I have chokes on everything from speaker cable to plugs, job done well and effectively. These are great for speaker cable. I placed the 9mm a few inches away from the speaker terminal on the amp and the same on the speaker end. The result was immediately notable with a cleaner better defined signal from the amp. Worth it!

Good mix of sizes. Connected as expectedb and performed as expected.

very well made did the job I needed it to do Good service

Fast delivery Nice set to have.

Average ferrite beads

A good variety of ferrite core clamps. Very useful for a noisy RFI environment.

I live in an area of high frequency disturbance.. think radio interference, or what really annoyed me (hearing highly mumbled radio or phone conversations) while wearing any sort of attached headphones, gaming is not fun. I bought these to attach at the wires and hopefully block out the noise, and it has worked and improved it significantly, i’d say about 90% if not completely.

Jag har inte fått några ring ferrit kärnor så jag kan inte komma med något resultat av den tyvärr
