Works with Studio Monitors

Reviewed in the United States on May 27, 2024

Used this product for a couple of studio monitors through balanced outputs generating a LOT of ground noise with a brand new cable coming directly from the computer it was connected to (possibly the network adapter or GPU).
Although this product is advertised for cars, it was an easy, perfect, cheap fix with no more ground noise coming from the studio monitors and no loss in audio quality.

Mine worked, really worked GREAT. I am shocked, but happy, would recommend to others.

Reviewed in the United States on March 3, 2023

I paid full price; I am not a professional reviewer or paid by Amazon or the manufacturer.

I have a speaker/subwoofer PC sound system made by Phillips. It has 2 speakers & a woofer, fed by a 3.5mm input jack. I had no noise until I added a splitter so I could have 2 laptops share the same speaker system. This is when the noise, which was hum & other random noise that was very apparent through the speakers. Even at low volumes, you could hear the noise, I might make a video to show how bad it was..

In the past I purchased a similar device to get rid of background noise, I think it was related to a USB powered speaker I used in the past. Well, the other unit did not work, and the noise persisted.

I am pleased to report that this model noise defeating device worked great. Once I plugged it in, the noise is 100% gone. Not reduced, but back to the way it was before I added the splitter. I am not sure why using a Y cable between 2 laptops would create this situation (the noise), but this device did what I intended it to do.

Just my experience, I am sure others will have different results. I am happy and I would buy this model again if needed.

EDIT: 1 month update: Still working GREAT! Like another reviewer, null/Toddi, said: "Noise from GPU and mouse movements, and background noise from the laptop especially full screen". That is exactly what I was hearing BEFORE I installed this device. I like it so much I bought a spare just in case. It eally kills the PC noise that comes from a desktop of laptop. I actually tried the USB powered speakers from before, and without the device the USB powered speakers pickup USB noise. When I installed this with the USB speakers, it once again killed the noise. Whatever "magic" is inside this unit, it really works. I was going to try a isolator power plug device and ferrite loops, but I am glad I tried this first. I think someone in the questions said that they tried the ferrite cores and ISO power to no avail. I would have wasted a lot more money if I went that route. I would suggest anyone with noise try this FIRST. The price more than justifies an attempt at letting this device get rid of your noise. As for killing low end, I do use Spotify to listen to 80's rock and jazz, and I have not heard any low end problems. I do have a woofer and 2 speakers/drivers in my Phillip[s PC sound system.

How to get rid of the hum! Plus a pro-tip

Reviewed in the United States on April 12, 2024

This thing does exactly what it says it does. The fat little section has an inductor that creates the magnetic field that makes sure when current (sound in this case) flows through it, it is normalized and doesn't have any potential difference (which causes the hum we all hate). It's cheap and works on the 3.5MM input that I plugged it into and no matter how much power I throw at it now, there is no more hum. A good buy and I recommend.

Pro-tip: Where do I put this thing in the sequence? The age old question of before or after that amp??? Well, conventional wisdom usually says add this inline as close to the amp as possible between the head (stereo) and amp. In other words, put this on the input side of the amp. Stereo --> Isolator --> Amp --> Speakers. This works in the vast majority of cases.

There are some instances where there might be components after the amp besides the speakers, perhaps some kind of Bluetooth adapter, or game console, or something. This situation is more rare but in that case you'd put an isolator after the amp (out put side) but as close to the speakers as possible so Stereo --> Amp --> Component X ---> Isolator --> Speakers.

There is also a third scenario where you put an isolator before the amp AND after the amp but before the speakers because you are getting two kinds of issues like potential current differences from a bad ground on the stereo feeding into the amp (corrected with the input side isolator) and then a shielding problem on the way to the speakers or another component that is leaking on to the line with a bad ground or the like (corrected with the output side isolator closest to the speakers).

Why not just add one single isolator as close to the speakers as possible to correct it all? I'm glad you asked. This is because unless you get super high quality and usually powered isolators, you can't expect miracles and the potential difference might get so high that one isolator just isn't enough to correct it all so you correct it one step at a time after each component that is causing an issue.

Bottom-line: One isolator on the input side of the amp or right before the speakers is usually enough and this thing works great for that.

It works, but at a cost

Reviewed in the United States on March 1, 2024

Product did exactly as stated, but the audio quality does take a hit. Feedback and static were gone, but the quality of the audio drops significantly.

It worked for the iPhone with power splitter

Reviewed in the United States on April 15, 2024

I bought a used Scion for a family member to use while home from school. The car has an aux plug, but for longer trips, the phone needs to be charged too. I used a power splitter for the iOS that allows the phone to charge while also playing audio through an aux cord.

With the lights on or AC running, there was a whine coming through. This low pass filter stopped the whine and the audio was clear.

Other reviews mentioned sound quality impacts or other sound issues. If you’re using this, it’s likely you’re not running a high end sound system. If you are, then you’re running Bluetooth or USB. I didn’t notice and sound deterioration while using it.

For the price, this was a great purchase and it very worked well.
