2 Packs Ground Loop Noise Isolator for Car Audio/Home Stereo System, Ground Loop Isolator with 3.5mm Audio Cable

This Noise Isolator worked instantly from loud buzzing sound to silents with a low hiss sound like 5 decibels which is nothing.

Used them to hook up a computer and a cd player to a mixer. The computer had a very noticeable hum before installing this device. Once installed the hum was GONE!

I use these on my Goldwing and Tundra aux input to completely remove that whine you get when plugged into the aux port. I use bluetooth aux adapters that are rechargeable. When they are turned on and not plugged in to charge there is no whine, but when charging there is a very annoying whine. These complete remove that and leave you with just what you wanted to hear. Get them.

It works as advertised and was the exact size we needed. We are using them for a 3 stream PC setup as duo streamers. We plugged them to GoXLR minis to our stream PC that runs OBS. Works well. Easy to plug in if you have the appropriate ports on your PC. Days later, we did have a cat try to chew on them and shockingly, no chew marks. This was the same cat that has chewed up the ends of our gym floor mats. Not saying these are the most durable but a little bit of chewing showed no signs of damage from our little heathens.

I have 2 laptops, a phone, and a tablet all connected to a little mixer that is connected to an amplified speaker on my desk when I'm working. The crosstalk from these devices is awful (laptops are notorious for this). I got four of these and connected three to three of the inputs and one to the output of the mixer (the tablet therefore being isolated from the rest as a result). The crosstalk is gone. The only noise is from the amplified speaker-which is the speaker's fault-so adjusting levels cut that out. Problem solved! These are bi-directional, so which end you connect to in/out doesn't matter. They come with a short patch cable, which in most cases you'll need. I chose to connect them close to the mixer for my situation. No power is needed as these are passive filters. I don't have a professional audio setup, so I can't pick out any issues with the quality; it sounds good to me!

Well I should have known as sounded too good to be true when I get a chance I'll cut one open and I'll get back to you guys and let you know where it stands but from what I can tell now let's just say if it was back in the 1800s I believe the company will be considered the snake oil guy on the back of the the horse and buggy selling a bunch of worthless medicine to innocent people that just can't afford to start with now forwarding it hpeople i I got this feeling there's nothing but sand or cardboard or whatever on the inside of that little magic block because it ain't so magic the bug the thing in it does not a darn thing compared to the way it was before you tried even connecting it seems to be an extremely expensive coupling well hope you have better luck but like I said I got a feeling there's nothing inside maybe a diode just to make it look good I probably didn't even solder it they probably super glued it and you know them guys

Installed this as a precaution when I added a turntable to my system. At first all I could say is that it did no harm. A few weeks later though my system developed a hum, which went away once I uninstalled the noise isolated. Therefore I will cease using and see if I can get a refund.

It's electronically a stupidly simple circuit any beginner could make, but the trick is containing it within a professional-looking, commercially-made housing that isn't made from a pill bottle or other reused container, and doing so for less cost than getting TWO of these for.... what'd I pay, eight bucks? nine? I have a Jeep with the aux audio port into which I have wired my amateur radio transceiver via a 3.5mm TRS patch cable. The alternator whine only came through on the receive audio, never went out on transmit, and honestly it was quite tolerable, but I really wanted to get rid of it. Knowing the circuit was a simple design, I figured it would be quite inexpensive to purchase a commercially manufactured product, and I was correct. Installation was a breeze, and fortunately I already have the radio bracket close enough I could zip-tie the filter to the bracket and keep it secured and out of sight. You can barely see it! It definitely works. After installation, I couldn't hear any whine. I'm not saying it's zero, but the engine with the tops off and windows down was loud enough that I couldn't hear it with the filter installed, whereas the whine was loud enough to hear through the engine noise with the filter not installed. I don't 100% understand the theory myself, but essentially it's a 1:1 audio isolation transformer inline that disconnects the lines electrically (DC) but still allows audio (AC) to pass electromagnetically via the transformer windings and core, thus breaking the otherwise direct connection between audio equipment and a variable ground potential (voltage on the audio ground instead of chassis ground) from the alternator. Anyway, bottom line, it works, and I have two for the same price some sellers are selling only one.

Compre 2 para calarlos y si funciono muy bien, en una consola de audio tenemos conectadas 3 computadoras y las cuales ocacionaban ruidos o zumbidos, utilizando este equipo en 2 computadoras esos ruidos desaparecieron a lo cual mandé pedir otro mas para completar el equipo que me falta

All the mouse noise from the speakers on my desktop pc is gone. No more noisy scrolling, works great.

Muy buen producto

I bought these to remove a hum I had in my Arcade machines between the source and the amplifier. I had a ground loop that these were able to completely remove without any noticeable issues to the sound quality. Perfect for my needs and I'll need a few others for my PC and other ground loop issues.

Funcióna bien ayuda a eliminar ruido eléctrico
