I paid full price; I am not a professional reviewer or paid by Amazon or the manufacturer.I have a speaker/subwoofer PC sound system made by Phillips. It has 2 speakers & a woofer, fed by a 3.5mm input jack. I had no noise until I added a splitter so I could have 2 laptops share the same speaker system. This is when the noise, which was hum & other random noise that was very apparent through the speakers. Even at low volumes, you could hear the noise, I might make a video to show how bad it was..In the past I purchased a similar device to get rid of background noise, I think it was related to a USB powered speaker I used in the past. Well, the other unit did not work, and the noise persisted.I am pleased to report that this model noise defeating device worked great. Once I plugged it in, the noise is 100% gone. Not reduced, but back to the way it was before I added the splitter. I am not sure why using a Y cable between 2 laptops would create this situation (the noise), but this device did what I intended it to do.Just my experience, I am sure others will have different results. I am happy and I would buy this model again if needed.EDIT: 1 month update: Still working GREAT! Like another reviewer, null/Toddi, said: “Noise from GPU and mouse movements, and background noise from the laptop especially full screen”. That is exactly what I was hearing BEFORE I installed this device. I like it so much I bought a spare just in case. It eally kills the PC noise that comes from a desktop of laptop. I actually tried the USB powered speakers from before, and without the device the USB powered speakers pickup USB noise. When I installed this with the USB speakers, it once again killed the noise. Whatever “magic” is inside this unit, it really works. I was going to try a isolator power plug device and ferrite loops, but I am glad I tried this first. I think someone in the questions said that they tried the ferrite cores and ISO power to no avail. I would have wasted a lot more money if I went that route. I would suggest anyone with noise try this FIRST. The price more than justifies an attempt at letting this device get rid of your noise. As for killing low end, I do use Spotify to listen to 80’s rock and jazz, and I have not heard any low end problems. I do have a woofer and 2 speakers/drivers in my Phillip[s PC sound system.

A few days ago, I ran a stereo cable from the headphone of my MacBook Pro laptop to inputs on my desktop audio mixer, intending to improve the sound quality by using my studio monitor speakers instead of the tiny laptop speakers. Unfortunately, there was a great deal of digital noise added to the sound. So I bought one of these doohickies, plugged it in, no more digital noise! Excellent results, especially for the size and price.

All that I needed was a solution to remedy an extremely noisy headphone jack. This is a simple task and there are many ways to do this, but I didn’t feel like taking the time to implement any of them for this task. I simply needed a quick plug and play solution that would get rid of the constant buzz and click so that I could listen to the device in question at a low volume and still enjoy the sound.This did the job perfectly. I can no longer detect any of the previously highly distracting noise while the desired sound comes through remarkably clear.Build quality seems solid and compact. As an added bonus, despite the order being placed after 10PM, the Ground Loop Noise Isolator was on my doorstep the next afternoon.

The AUX port on PS5 controllers gives all of my wired headphones an annoying hiss that drowns out the quieter noises. This works perfectly in eliminating that and consequently improving the sound quality. Would rate five stars if not for the fact that it does prevent using a headset microphone, as the connector is only TRS.

I have an Echo Auto 1st generation in my truck. Not to be confused with Android auto that comes pre-installed in newer vehicles. Echo auto will work with older vehicles without a display. It adds “Alexa” features, where you can ask for directions, ask her to play music, navigate somewhere, what time McDonalds is open till, make calls etc… All hands free. There has always been a high pitched whining noise. The faster you went, the louder and higher pitched it got. People you are talking on the phone hear it and get really annoyed. Been meaning to order this product for a long, long time, just kept forgetting. Works A1!!! You can have it plugged in and Crank the radio volume all the way up, and it is TOTALLY SILENT, just like the radio is not turned on!! Well worth the $10 (as of this writing) price!! Wish I would have bought this thing years sooner. Wife is happy when I call her hands free now!

I listen to music and various audio from my cell phone while connected to my car stereo using an aux cord. I’ve noticed that I hear a very annoying static feedback whenever I’m trying to charge my phone, or have my headlights on, and I’ve switched to numerous different types of USB chargers to see if that would make a difference. This ground loop noise isolator allows me to listen to the car stereo with no more buzzing or hissing or feedback noises. It took a few seconds to install. Glad I found out this kind of item exists.

My soundbar and my echo dot were plugged into a common power strip. Noise was horrible using aux cable, but was clean using blue tooth (aux cable produced a ground loop). I wanted the aux cabled connection because blue tooth would disconnect when soundbar powered down. This thing worked perfectly. I’m pretty sure my power strip is noisy power. I run the Alexa directly off of a USB power port on the power strip (no “wall wart” usb power adapter). The Vizio soundbar was plugged into a standard AC power outlet on that same strip. Bad noise. This gadget did just what I needed. Alexa sound now overlays nicely with soundbar seamlessly with no buzz or noise. Voice assistant mode on Vizio is quite nice in this setup.

Had this awful, irregular buzzing/blips/feedback sound from my headphones while using my PC. I connected this doohickey between the speaker jack and my headset and the sound is completely gone. I’ve been using it for a few months. Massive quality-of-life improvisor just a few bucks, no more head.and earaches.

Cumple su función a la perfección.
Había instalado un sistema de video conferencia con audio de techo, en la sala de juntas de un cliente, se me presento ese problema de ruido de fondo, un zumbido muy feo, estaba muy preocupado y escéptico si me iba a servir este producto, pero por arte de magia al conectarlo se quito el zumbido, producto totalmente recomendado.

Does the job very well, no hush, no hum now
I have a Linux laptop and I connect a boom box to its audio output. With all my USB hub and USB connections, and possibly because of Teams, while using the same power circuit for both, the hum was too intense to be able to use the boom box. Adding the “BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable” cut the hum completely. I only hear some clicks when an audio using application starts. I have no issues listening on Youtube.

Un miracle !
Pour ma part, cet objet est mon sauveur ! Un affreux bruit ground loop venant du GPU de mon nouveau pc m’empêchait littéralement d’utiliser mes enceintes, le bruit était insupportable. J’achète ce petit connecteur sans grande attente mais alors wow je suis bluffé ! Pas un bruit dans mes enceintes sans impacté la qualité du son. En plus d’être efficace il est très abordable, l’autre solution avec un behringer hd400 et deux câbles symétrique revenait à plus de 50€ contre 13€ ici ! Si vous avez le problème aussi, vous pouvez clairement essayer, y’a des chances que ça règle votre problème !
