Conext Link RCA Stereo 2 Channel Ground Loop Isolator Signal Noise Filter Suppressor Reducer Alternator for Car Audio Home Stereo（13600）

This worked on a sub that was humming. I’m happy. :)

I've always had this annoying computer noise from my monitors connected to my Focusrite scarlett. Using headphones I get no noise, but when I connect the Rocket 5s I get random high frequency hissing. I tried most of the suggested tricks but none worked. I was 100% sure this was computer noise because other devices connected to speakers are fine. I did not hold up much hope for this device as it was cheap but to my surprise it worked great! Noise completely gone.

Did the total opposite of what was required. It actually amplified the buzzing. An awful product. Bitterly disappointed.

The device is compact and requires no power. I am not an expert to review this and was not at all sure the issue in my audio system was a ground loop, but duly inserted into the audio lead, a background rumble noise is now gone or substantially diminished.

then this product works like a charm, however will reduce your bass, had to increase the subwoofer gain which for me was not a problem

Had to go from balanced to unbalanced connections to add a small subwoofer and got static hissing from my studio monitors. Saw this and though why not try it.Added it in between the audio interface and sub made it a lot worse but then changed it from sub to speakers instead and it fixed the static. Definitely reccommend giving it a try. Nice affordable fix.

No need to disconnect the earth wires

Every time I would listen to my stereo at a low volume you would hear engine whine and this did the trick no more noise 5 Stars from

I bought a boss amp to power my door speakers in a Dodge Magnum SRT8 and after installing the amp I had constant engine whine and just a high pitch squeal. Took a chance on these installed them and the engine noise and extra noise is all gone. Works great.

Had the worst buzzing humming coming through my speakers.. this totally did the trick .

With the new stereo, I had an unbearable whistling noise while the engine was running. I installed this in 5 minutes and all the noise was gone. I like it! I will highly recommend this device!
