Golvery Ground Loop Noise Isolator, 3.5mm AUX Noise Filter

Got this to see if it would fix the noxious audio from a W-King D8 Bluetooth speaker as it powered a Critter & Guitari Organelle using a MyVolts RipCord while amplifying it's audio output. This fixed the problem. I recommend this If you find yourself using USB to power an audio device, and find that there's some yucky noise creeping through the audio output signal. Prob'ly fixes similar issues with Korg Volcas and other small portable synth gear. Will also work with guitar pedal board power units when using them to run similar devices.

Did exactly what I needed. No more hum.

It is a little larger than I expected in size and the adapter wires can make a heck of a noise if they move. Once its pluged in and stationary this works like a charm.

Piece of junk. Sure, it kills noise, but there is nothing from the left channel. Do not recommend.

Works as advertised.

It works. I had to find the right place to plug it in, not at the end where the headphones go but out of one of the sources. It reduces the ground loop noise down to barely noticeable when there's no sound coming through the headphones. Allowed me to hook up two audio sources (Laptop and Switch) to the same headphones. Just works, no complaints so far. I did notice a reduction in volume from the source that has the isolator on it. I didn't expect as significant a drop as I ended up with, but it wasn't something that I couldn't easily overcome. I have an amp on that line anyway and it wasn't pushing too much out. Had to bump up the volume a little. With the phones directly plugged into the source only, the sound quality is noticeably better and definitely clearer. But I'm not listening to anything critical... just a laptop voip conference calls and a Nintendo Switch or whatever else is outputting from another monitor, sometimes a phone.

It did not work for me at all but they sent me a replacement right away. That one didn’t work so they refunded my money completely. Great company but crap product

I purchased this product because the cable which connects from my blue yeti to my a50 base aux had some kind of electric interference and would hum. It has a good weight but not enough to pull cables or weigh down too much. Immediately it silenced weeks of distraction during my streams. I recommend it! I bought 2 because I plan to podcast and noticed another mic also had the issue. Worth the money!

I use this to connect my switch to the USB audio interface connected to my desktop pc. It works well and the build quality is good for money.

Works perfectly for my Nintendo switch to my PC. No more audio interference.

Used with an aux cable plugged into a Nintendo Switch connected to a PC via line in. Removed the ground loop noise!

I recently upgraded my PC speaker system to some amplified high powered monitors. In doing this, I picked up some very annoying buzz/noise that plagued my experience (especially at low listening volumes) All I could hear was a constant faint buzz, and also whenever I moved my mouse around, I could hear another high pitched whine on top of the buzz... I tried changing cables, using ferrites, re-routing cables, then switching between my speakers and PC using same power source, then different source... Nothing worked. I searched more YouTube for answers. I found a video suggesting that I get a ground loop isolator... Could this thing be the cure? And for less than $20? INDEED YES... I injected this device into the path of wire that connects my PC to the amplified speakers, and I was ASTONISHED... BLOWN AWAY... There was NOTHING... Pure silence. This thing is MAGIC. I can't say that this is the solution for every single type of noise than can creep into your audio signal, but this simple little pass-thru dongle-thingy blew ALL my problems away!

Wow had unreal Buzzing with my new KRK speakers. Ordered this for 10$ eliminated it all. Well worth it.
