BESIGNGround Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable

This is an excellent product (Ground Loop Noise Isolator) to use if you have any type of device that has unwanted sounds in the audio, such as a hum, or buzz, or stray radio signals. I bought two of these, one to plug into a TV sound bar (which had this horrible hum or buzz that started growing louder each time after I turned the sound bar on, and this device immediately fixed the problem perfectly as soon as I pugged it in to the audio line between the TV and the sound bar.. I plugged the second one that I bought into an audio cord coming out of my desktop computer that goes to computer speakers. These speakers had a hum in them, but they also picked up soft talking that sounded like it was coming from a far away radio station. This immediately got rid of all of that unwanted noise and interference, resulting in the excellent, clean sound quality that I wanted. I highly recommend these. I had tried all kinds of other things in an attempt to get rid of those audio noise problems, with no luck in the past. But this device fixed it quickly, and it was inexpensive, and extremely easy to connect.

I bought a new UGREEN shielded aux cable to use with my Sony WH-1000 XM4 headphones for my Rodecaster Duo, but I noticed a problem - there was this awful static noise. I did some research and found online that something called a "ground loop noise isolator" should fix it, so I picked this one up from Amazon and tried it out.Sure enough - it works! I got this for $8.99 and honestly I'd say it was worth it.In a separate case, I noticed an issue when using my Samsung J Series sound bar in my living room with my Dell Latitude laptop. Sometimes I would hear this awful loud buzzing noise, and I especially noticed it if the aux cable was plugged only into the soundbar and I touched the other (unplugged) end with my hand. This also happened while the laptop was connected to the soundbar at some point. Realizing that I was probably making ground with the connection, I tried to use this product for my laptop and the awful buzzing noise went away.Hopefully this review helps!Extra Information:As for why I wanted to connect this laptop to my living room sound bar, it's because I use it as a server running Rocky Linux and I set up a cron job to play a custom alarm sound every morning at 8:00 AM (cronjob syntax is 0 8 * * *) using cvlc (CLI VLC Media Player) that I created, which counts down from 20, then counts down from 10, and then fades into an extremely loud air raid siren. My reason for doing this is because I sometimes fight with myself to get up in the morning, especially if I stayed up late, so hopefully this will help me get up sooner. I'm going to buy a second one of these so I can have one for my Rodecaster Duo and one for my Samsung J-Series soundbar that's connected to my Dell Latitude 7400 laptop.

I have 6 of these and they work EVERYWHERE I put them. This one I used in my Jeep. After I put a Ecoflow Delta 3 Plus in the back of my Jeep I was getting a loud buzz from the aux input from my computer output. I attached this and the buzz was completely gone. I used these at my business, at my home, and Jeep they are awesome.

Kind of a weird use case, but I wanted to route audio from an Xbox to the same Bluetooth headphones connected to my computer, so that I wouldn't have to keep swapping to different headphones or mess with aftermarket Bluetooth transmitters for the Xbox controller. There was also the added benefit of being able to listen to both PC and Xbox audio at the same time.I did this by connecting the Xbox to my monitor with HDMI, then connecting an audio cable to the headphone jack from the back of the monitor directly into my computers microphone input. Then enabled "listen to this device" in the microphone settings in windows. It worked, but it created a very annoying buzzing/static sound and a high pitch squeal when the volume was turned up.That's where this device came in. I connected the isolator to the back of my monitor first, followed by the audio cable, and into the mic jack of my PC. I found this reduced the noise by a significant amount, and after adjusting the level of the microphone to about 80%, the noise was pretty much completely gone.If anyone is trying to do something similar, there is a very slight delay in audio when doing this in windows. That is not the fault of this device though, which has worked perfectly for me.

Using this with my portable amplifier. Line noise was really loud but this device eliminates approximately 80% of it. Shame it doesn’t cancel out 100% of it but since I’m using it to practice electric bass/guitar when I’m on the go eg. pool, park, traveling, it does the job well enough. If you’re going to use this heavily, it’s do not recommend.

Purchased Edifier MR4 Speakers and Presonus Eris Sub8 Subwoofer to connect to my PC. The Edifier alone had no humming/buzzing noise but once I added the Subwoofer, I had this really annoying noise when the volume was up. It was also very apparent while playing games. I played around with the volume from my PC and speakers to see if I could get rid of the noise but it would have to be set really low. What's the point of that? Anyways, I did some research and there were several reasons for the humming noise. The one solution that popped up often was using a Ground loop noise isolator. So I immediately went on Amazon and purchased this one since it had the most reviews. I connected my RCA to 3.5 mm jack to the ground loop isolator and then to my PC and low and behold, the white noise is gone! I can now enjoy my music and my games without the loud humming/buzzing noise. If it wasn't for this product I would have returned my subwoofer.

Device got rid of a ringing sound that occurred whenever I hit accelerator. I am very pleased it has not affected HD music service quality. Sounds great with perfectly silent background.MBZ SL 550, Amazon HD music through 32 bit 384 khz DAC.

Did the job ! I was so happy this omitted my buzzing noise when I wanted to listen to my music from iPhone to my car ! Wish I would have found this sooner .
