Golvery Ground Loop Noise Isolator, Auido Humming Hissing Buzzing Noise Filter Eliminator for Car Audio, Home, PC Stereo System with 3.5mm or RCA Aux Jack

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.

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.

Easy to cleanly install with a sticky-back mount and zip tie!Included cable is perfect length!Got rid of 95% of audio hum, but hum is still 5% present in "silence."

I used this to get rid of the noise in our church system. I have our Zoom and streaming computer hooked into our PA system for sound. The computer screen was introducing a lot of noise over our PA system. I installed 2 of these units in line with the input and output of the computer and the noise was gone! There are more expensive options out there but this solved our issues much more inexpensively.

This thing did wonders. It really isolated a lot of noise on my audio line but after awhile, the right channel has been slightly cutting out and now I have to make sure it's perfectly still and seated correctly in order for it to work. I have taken well care of this thing without any abuse and I think the quality of it just went to heck fairly sooner than it should have. It works nice until there is a short in the connection inside the device.

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

Worked as advertised. very simple install.

This product does exactly what I bought it for, removing the buzz from my car stereo when something is plugged into the auxiliary jack. I wish I had bought it years ago.
