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

Works! Had a buzz (ground loop?) connecting a PC audio output to a mixer. This fixed the problem.

Eliminated noise whining issue in car while playing aux cord. Essentially did its job. Love that there are 2 so I can run this in my other car. Great stuff.

Plugged both sides into my pc connected to the TV. Before the speakers had an annoying underlying buzz. After it was silent and only the audio I want comes through!

The media could not be loaded. This is a pretty good product, nothing too insane, the value is good, the installation is extremely simple, and to be honest, I thought it would be way bigger, the size of it is very small which is what I like, I stream on twitch and this helps a lot with hissing sounds and buzzing. Sounds whenever I use my mixer. One little problem is that it does make audio slightly quieter. Other than that, it does what it says it does, and it’s nice to have. 👍

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.

Reduces buzzing noise but also reduces sound quality and volume by as much as 40%I would not recommend this product.Returning this item is not an option because Amazon.com charges nearly as much for the return as the cost of the item.

Had a 4 channel headphone amp and every device connected to it had a hum.Installed this on every input and got a clean sounding system again.Truly don't understand why these aren't built into every audio input gizmo. If it's a known fix, design it into your stuff and the. I don't have to buy extra gizmos, cables, and connectors.This had two 3.5mm jacks on it, so had to get 1/4" adapters at all ends to make it work.

This product does remove ground loop noise. However I was confused at first because I plugged one in and it actually made the problem worse and cut my audio signal as well. After trying everything I could think to try, I finally just tried using the other one that came in the box, and it worked like a charm. Not a big deal considering it’s such a cheap electronic accessory.
