Jupi-storm Ground Loop Noise Isolator for Car Audio /Home Stereo System with 3.5mm Audio Cable(Eliminate Audio Noise Completely while Playing music) (G01)

I've tried a bunch of different ground loop noise isolators for different scenarios. Few if any have seemed to really make any difference and I was starting to wonder if any of them work at all or if somebody was playing a very elaborate joke on me. I figured I'd try again with this little device.I've been living with an ANNOYING buzzing/hum in my car for over a year. The setup is that I have a 3.5mm male cable going into the AUX input from a Bluetooth receiver. The hum is coming from the power supply that charges the bluetooth receiver. When I unplug the receiver, the noise stops...this was fine, but after a while it got to be very annoying to have the receiver power die on my and I'd have to wait until I was stopped at a light to plug it back in (of course when this would happen, every light would magically be green...because I'd be waiting for one to be red).Anyway - I plugged this device in between the AUX plug in the car and the 3.5mm male plug of the Bluetooth receiver. I'm now able to enjoy buzzless music in the car without worrying about unplugging/replugging the power. I know this is a "1st-World-Problem"...but this adapter was an inexpensive/simple fix...Bottom line, I learned that audio problems I thought were ground loop buzz issues in the past probably have been caused by something else...and in this case it really was a ground loop issue causing the noise in my car....and this device stopped it.

Using ham radio equipment in my home I was troubled by interference on my computer sound system every time I transmitted a signal. I tried numerous different ways to eliminate the interference but without success. Finally I came across this Ground Loop Isolator and decided to try it. The sheer simplicity of the device and its small size made it very easy to install. To my amazement it worked and all the interference was completely eliminated. Best of all, there was no discernible change to the music being played on my computer. The simplicity of installation and reasonable price made this a "must have" device for me and I immediately ordered a second one for another similar situation. I enthusiastically recommend this product without any hesitation as an excellent, simple solution to a difficult problem.

Replaced a similar isolator for my Bluetooth connection in my car. This one seems to add more bass than the other did. I found that it was still an acceptable amount of bass when I turned down the settings on the radio. I mainly listen to my phone in the car so it's not a big deal the radio channels are now a little bass lacking with the settings turned down.

The included cable is about six inches long, or maybe four inches of actual cable between the plugs. I'm not using that; I needed longer cables to mount the thing in a reasonable spot on my console. One day I bet I'll be happy to have the little thing stashed away. Mounting was aided by the flat sides. The corners are rounded but it's an off-square profile rather than a circle. Having done that, it works great. I would bet every one of these similar items on Amazon is the same until printing a brand name on the side, so if this is the cheap one of the day, have no worries.

Did not work for me. I plugged in both directions since there was no input/output labeled. It acted almost like a high-pass filter, causing the low-end to sound completely distorted. It did stop the buzzing, but it also stopped the music. :(

My old cassette deck had a hum when played through my stereo amplifier. So I got the right adapters, used this between the cassette deck and my stereo amplifier, and the hum went away. I guess I had a ground loop problem between my cassette deck and my stereo amplifier.

Easy to use, just plug phone wire into the larger side, plug wire end into car audio input. Set car radio to AUX to hear your iphone music. Eliminates the annoying whine from auto system interference

It's a little bit bulky, but it gets the job done, and I no longer have any problems with ground noise making it into my car speaker system. I would recommend getting a longer 3.5mm male-to-male headphone cable, though, depending on your use case, since the included one is very short.
