Get rid of pesky ground loop noise with a simple connection!

Reviewed in the United States 🇺🇸 on September 19, 2022

Verified Purchase

Honestly such a lifesaver, I was getting annoyed by the constant humming in my earbuds and headphones when I am on my pc, even with no sound playing.

I got two of these (one per input into my audio mixer) and- like magic- the hums and buzzes of the power of my devices manifesting in my audio is gone!

Honestly don't know how to recommend these more or write more about them. They are so simple, just a cable you plug your 3.5mm audio into and then feed the other end into your mixer or audio output device. What's not to love?

I have a triple PC gaming streaming and recording setup. I also have a sound dac connected to the gaming PC as an additional sound amplifier. I had a terrible buzzing from the DAC from the day of purchase. As soon as I used this device to filter out the buzzing from the line in ports all external buzzing went away immediately. This device is cheap and so worth the money. I can go back to streaming and recording without worrying about my videos having a horrible buzzing noise. Thank you!

So much frustration with ground loop.. I was about to purchase a rather expensive UPS and buy fresh new fancy cables... but figured I'd give this cheapo thing a try... and sure enough, it 100% fixed my noise issue. A year+ of frustration gone instantly as soon as I plugged this little piece of magic in.

I can't say for sure sound quality is 100% original, but it sounds a f ton better than the noise i was hearing with the ground loop.

Worked perfectly!!!

Reviewed in the United States 🇺🇸 on August 17, 2022

I was installing an aftermarket roof TV for my minivan. The one that I bought is for 1080 P but the only sound you could get was from the radio or from IR and the radio would get Static depending on where we traveled. The IR received interference every time somebody moved in the van. So I hooked up an HDMI audio extractor which uses an AUX plug and hardwired it into my vehicles AUX wiring. My problem is we would get a humming noise that would increase to the speed of the throttle. This particular part completely eliminated that. It does not matter which way you plug it in whether you do it according to the photos or backwards from my particular situation they both work! No more feedback. THANK YOU!!!

I bought this to fix the loud white noise that would be emitted when I plugged in my PC to the aux port on the Astro A40 Mixamp while also being plugged in to my PS5. This isolator fixed the white noise issue and now I can use both my PS5 and PC at the same time without audio problems.

I can't speak to the durability and longevity of the product yet, but it works great! No more noise or whining. I am using this for a usb C splitter that charges while an audio USB c is plugged in. Had a whining noise from being plugged into the cigarette lighter charger.

I'm piping my Switch audio through my PC via the line-in port. Previously, there was a constant buzz/hiss in the background due to electrical interference. This device has completely eliminated it! It's small, lightweight, and works exactly as described. I highly recommend it.

Works with ATEM Mini

Reviewed in the United States 🇺🇸 on September 7, 2022

My ATEM Mini Pro ISO had a bad hum when connecting to the computer via USB and using the mic in port. The issue could not be resolved by using any good insulated cable. Finally I bought this and put it just before the ATEM 1/8 mic input, the hum went away. Good product, does what it is supposed to do.

SO HAPPY

Reviewed in the United Kingdom 🇬🇧 on October 12, 2018

Verified Purchase

I'm using a 12v car subwoofer connected to a pc, with a separate 12v power supply powering the sub. A bit of a nightmare to get working properly, but it eventually worked. Except for the INFURIATING humming sound coming from the speaker. I spent two whole days researching what could be causing it, and tearing the whole room apart to try different configurations to see if it would eliminate the noise. If anything, it only got worse. So many sleepless nights thinking about it, and hours of listening ruined by the incessant hum. Eventually came across these "ground loop isolators" and ordered this one. Eagerly awaited its arrival while making do with my soul destroying humming machine. It finally arrives. Now, normally when I switch on the sub, the noise begins blaring immediately, especially when the pc is off. So I set up this little beauty, switch on the sub and.....silence. Deafening silence. I checked the sub, thinking it wasn't after switching on. It had, but not a peep from it!!! Totally eliminated the hum! I immediately started laughing and dancing with joy, I think that's the happiest I've ever been in my life, to hear NOTHING. Buy this little thing, even if you don't have a problem it can solve, because it's just so satisfying holding something that just *works*

It does *something* but not enough

Reviewed in the United Kingdom 🇬🇧 on October 5, 2018

When I plugged this in, it changed the frequency of the noise, but it doesn't eliminate it right away. The loop noise did eventually disappear, so I kept going with it to see if it just took time for it to work, but it needs this extra time on every startup. The main reason I got it was I have a ground loop noise in a stereo system which only comes through when it goes onto standby, and if I listen to something while I go off to sleep, the noise it makes when it goes onto standby wakes me back up again! So for me, it needs to eliminate the noise right from the first squeak. If you don't mind it taking several minutes to take the noise out, it might be OK, but it didn't work for me. Also worth noting that although the product descripion to indicates that it was designed for a car or home stereo, the instructions are all about where it should be added to the car stereo circuit, so perhaps it was never designed to work on a 240V AC loop noise? Mine is going back.

Waste of time

Bought this to cut out buzzing in car AV socket. Firstly I plugged it into AV socket in car, then plugged in AV lead from my CD player.
Buzzing still there from car speakers. Then I tried pluming this directly into the CD player, then put in the AV lead to car socket.
Buzzing still there. So a complete waste of time.
Will be returning it to Amazon for a refund ASAP.

Bought this to eliminate the grounding buzz when I had my MixAmp hooked up to my Xbox Series S through USB and my PC through Aux, there is still some slight fuzz when I have the volume dial on the MixAmp cranked high enough to the point that any noise will physically deafen me, but at my current settings where audio is more than loud enough it has completely eliminated the grounding buzz.

Makes the hum louder!

Reviewed in the United Kingdom 🇬🇧 on November 9, 2018

Verified Purchase

The only thing good about this was the fast same day Amazon delivery. I bought this to try to eliminate an annoying hum from my external TV speakers. I suspected the problem was ground loop related as I am powering the speakers on a separate power socket from the TV. After plugging in I was somewhat surprised to find that the hum was actually louder than before. What a complete waste of money.
