ZIOCOM Ground Loop Noise Isolator, Noise Filter, Eliminate The Buzzing Noise for Your Car Audio System/Home Stereo with Jack 3.5mm Audio Cable (1 Pack)

I bought a new powered subwoofer to use with my PC. I didn't have problems with a lower wattage subwoofer I had previously used in the same manner but for some reason the new one picked up super annoying buzzing noise, EMI I guess. I tried rearranging my wires to keep them clear from all power cords, putting the sub and the PC on different wall outlets, getting better quality cables and using ferrous barrel chokes on virtually everything, but the noise persisted, especially when ramping up the 4080 GPU or using 2.4 ghz wireless mouse and keyboard, any movement on the video monitor screen made the racket increase! I was frustrated and getting ready to give up on the subwoofer when I saw this product recommended in a Reddit Sub, and it was like $9, I thought worth a gamble. Glad I ordered it because it has 100% solved the buzzing problem! All I had to do was plug it in line between the motherboard jack and the cable to the subwoofer. Couldn't be easier than that. No more buzzing at all! With the Loop Noise Isolator installed I can't perceive any difference or degradation in the quality of the sound from the sub or the monitor speakers I have run off from it, they all sound great. I love when a product does what it says it will.

Had never really even heard of these, but not expenive so decided to try one. They really doincrease the clarity of sound from a computer speaker!

Works great just how it should

These work GREAT for getting that buzzing noise out of your audio, but the biggest problem is that these don't solve the actual of issue of components using the same ground. This filters out the frequency, but also filters out some of the sound waves you still want in the audio, so you may notice some of the low-end is being diminished. If you are just doing audio books or talk, these are great. But since I'm an audiophile I just didn't like it!

Great product. Worked perfectly.

I had one of these installed for several months now. Yes, I can hear a drop is buzz especially when charging my phone and connected to my car stereo. I am using this in a project to add a mobile screen to an older vehicle and found out by running a left right test (from YouTube) that this does NOT separate the channels. You still have sound coming from the right speakers when only the left should be playing, same with the right. I am guessing they have something miss wired inside the unit.

My pc powered speakers always seemed to hum and pick up PC “noise” no matter what volume they were set at. This completely eliminated that hum and noise. Dead quiet now when no sounds are being played. Worked great for me!

Almost fixed the noise! It was bad though, now I can deal with it.
