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)

It did the job well, and makes my audio system safer. My analog, non-powered audio input line was getting run over by the powered audio line sharing the same speaker, and this took down the powered line to the analog inputs level. Now they both play nicely!

WORKED - for my SDS100 when I would go to charge it from USB cord while plugged into my 3.5mm jack in my head unit, i would get a loud explosion of RF frequency and popping from the engine, even when the car wasnt running, sending RF through the USB 12v or maybe the 3.5mm jack (im not sure). But when i connected this then connected my 3.5mm jack to my Uniden SDS100 scanner in my car it eliminated ALL of the RF and popping when charging at the same time! AWESOME! sound coming out of my SDS100 scanner is clear and sounds great!

It worked well getting rid of the noise on the intercom in my airplane. I can now charge my iPad and iPhone and hear alerts from the telephone.

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.

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!

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.

It works but it cuts the volume down and impacts the bass response

Works as intented. Bought it to get rid of noise floor with iems and did just that. No more static
