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)

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!

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.

The ZIOCOM Ground Loop Noise Isolator has completely eliminated the annoying buzzing sound in my car’s audio system. It’s simple to use—just plug it in between the audio source and speakers, and it works like magic. The compact size makes it easy to tuck away, and the build quality feels sturdy. My only complaint is that it doesn’t come with longer cables, which would have been more convenient for certain setups. Overall, it’s an affordable and effective solution for audio interference issues.

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 set up a new desk and when I plugged in my Bose speakers, I received some feedback. I thought the feedback was coming from the way the wires were hung so I tried to change them but I still received the bussing noise in my Bose Headphones and speakers. I tried moving the power from the wall plug in to a power strip and it did work for day or two but then started back up. I saw this product and thought I would give it a try. I does make the buzzing noise reduce by at least half but it also reduces the volume of my system. Here I am, listening to music on YouTube on a Friday night wondering why it is so quiet. I remove the device and, "Pow!". The volume increases significantly. I can't hear the buzzing through the volume when listening to music. so no harm. I had hoped this product would improve quality. It did not. For the price, give it a try. For me, it is a failure.

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!

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