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.

Works well but with some caveats, namely that it somewhat clips the low-end and introduces some distortion. It's most noticeable with talking (podcasts or scenes without background music of noise). I found adjusting the volume input seems to help but it really depends on the content so your experience may vary. It does do an excellent job at killing line noise which is the primary reason I got it.

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!

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.

This product is absolutely amazing if you're a content creator or you just need to listen to or record something. It completely gets rid of unwanted noise without hurting the quality of the audio itself.

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