🔇 MA Audio Ground Loop Noise Isolator: Enhance Car Audio/Home Stereo System Quality (Black) Review

It didn't work at all, I still had a squeaking noise when my phone was connected to my car's aux input through this item. In fact, when I took the device back out of the system, the noise went down a bit.

I had an extra cable connected from my PS4 Pro controller to the line jack on my PC to record (and listen to) audio from the console to the PC - with no noise whatsoever /hum gave noise . Once the cable is connected to my computer through this ground loop, the hum goes away, so everything works.

Firstly this device removes the hum that was in my car and the sound is very good. The price is good too, and when it stopped working 18 months later I was ready to buy another one. I recommend signing up for a free extended warranty when available (2 years). I didn't, but that was my fault.

Can't believe it took me so long to get one of these. My sound is absolutely perfect now when I charge my phone and use the AUX cable at the same time. If you have a Bluetooth system, this isn't necessary, but if your old car is online, this is the best $7 you'll ever spend on a sound quality upgrade. ALL loading noises are even gone and there is no degradation of the music itself.

My mixer was picking up horrible noises from my graphics card on a PC. I tested them and they completely eliminated that noise. I've bought enough to use on every line of this blender and it's a life saver! I have 6 connected. My office audio system wouldn't work without using them for noise cancellation. I didn't notice any significant change in audio level or quality other than the filtered out digital noise.

It works like a charm and it works so well I forget it's even there. I have a Samsung Galaxy S21 Ultra that only has a USB-C port, so I use a splitter adapter to charge it and listen to music in my truck at the same time. This causes a ground loop that results in a BIG hiss when I'm trying to enjoy the music. However, this little device solves the problem and I can listen to music and there is no hissing anywhere!

wanted my media center to run as smoothly as possible, I connected my switch to my computer to get some noise from the switch into my headset which also has computer noise (music, discord, etc.) reproduces. the problem do i get this loud annoying buzz from the noise of the switch? This is a common problem and it's not that easy to find a fix for it, but it works great and now all I hear is the sound switching and no constant buzzing.

I have a particularly difficult setup. I have a TV that sends audio to my headphone dock that wirelessly sends audio to my headphones. I got a huge electronic high from it and it cut it down immediately. I also bought a second one for my office desktop where I get audio from my work monitor to my main desktop PC to mix audio with my personal and work sounds. There was a lot of hype there too, but that absolutely took it away. Amazing product especially for people like me who hate that extra…

My microphone is plugged into a mixer that is USB connected to my MacBook Pro. I use a Canon SL2, which I also connect to my MacBook Pro via USB to control the camera with Canon software. I connect an audio cable from the mixer to my Canon camera so I can feed audio straight from the microphone. When both devices were connected to the MacBook Pro via USB, I had a canon-picked hiss that was very loud even at the lowest setting of the preamp volume in the camera. Thanks to this ground loop…
