ライン入力のノイズに悩まされていたがどうやらグランドループ由来だったようでこれをかませたら全く気にならなくなった

Works great. No irritating whistling noise when using car USB to power my portable CD player in my playerless car.

This product is a joke. It doesn’t work with anything that has any high power amplification. I suggest it’s only good for small stereos indoors, like a radio that you would buy back in ninth grade, when you thought, "This is a badass Sony or AIWA." You know, back in the late 90s and 2000s when that stuff was kind of cool. Other than that, this thing is a turd, a turd muffin. I don’t even want to look at it. What a disappointment.

I had really annoying feedback coming from my computer to my studio monitor speakers. I will probably get an audio interface at some point but in the interim I am running 3.5 mm to RCA. Yes these cables are not great for audio but its what I have at the moment. The noise was completely gone when I tried this adapter. It was an inexpensive fix.

tl;dr: it works, and cleared up the signal for those mobile/portable airplay car stereos so much that the sound is clearer that connecting directly to the car stereo via USB aux. Didn't expect it, give it a try if you really wanted your stereo to work but the bad background interference and noises made have you ready to send it back.I don't want to shell out money for a real stereo system yet so I bought a mobile stereo device. The stereo was good but had really bad interference and noises with when connecting to my stereo via 3.5mm aux. I prefer connecting to my stereo with either 3.5 or usb aux because the sound quality is much better than a regular bluetooth connection (at least for my car). That noise had me ready to return the stereo which was a bummer because it did carplay and stuff really well at a super cheap price so I decided to give this ground loop a try as I read one person saying it helped for them and I thought it was worth a shot. It totally works, against all my expectations this thing not only made the aux totally clear for the portable car stereo, but when comparing it to my preferred usb connection quality I found that it the USB actually had more background noise. Somehow, connecting my iphone to the stereo via bluetooth, with this thing connecting the car aux, it sounds better than my phone's direct usb aux connection.I tested it by playing back the same sections of a song on both USB directly from my phone to my car stereo and with this filter between the aux of the portable stereo into the car 3.5mm aux connections multiple times, and also when the song was paused turning the volume up all the way to listen for any background/interference sounds. The interference totally disappeared from mobile stereo into the aux and I then realized that my previously preferred usb connection had a ton of noise in the background because of the comparison.Hope this helps, this thing totally cleared up a horrible signal.

Works as intended, but the wires must be bent in order for it to work. Sometimes during livestreams it will loosen and make a horrible noise. It can be tricky to fix this issue. When the connection is not an issue, there is a noticeable improvement in quality from the raw audio.

Fait tres bien le job entre la prise jack 3,5 de l'autoradio et un systeme android posé sur tableau de bord .Le son parasité en permanence avec un sifflement en fond , depuis c'est nickel et sans aucune baisse de volume comme j'ai pu lire avant l'achat .Pour moi top !

Werkt goed. Ik heb een situatie waarbij ik het apparaatje kan wegstoppen in de opklapbare armleuning van mijn auto, omdat de aux aansluiting daar zit. Het lijkt me wel een storend ding om direct aan je telefoon te hebben hangen.

Con questo aggeggino credo di aver risolto definitivamente un problemino che avevo, cioè un fastidioso rumore di fondo dovuto al collegamento di un adattatore bluetooth al jack audio della cassa che tengo in salotto. Si collega molto facilmente: in pratica fa da ponte al collegamento audio. Una volta collegato e testato, ho notato subito un ottimo abbassamento del rumore di fondo: non lo elimina completamente, ma diventa molto molto basso, fin quasi ad annullarsi se si tiene il volume molto basso.Non l'ho provato in altri contesti, perché l'acquisto era finalizzato a quello, pertanto mi ritengo soddisfatto.Il prodotto è un Amazon Choice quindi ho fatto un acquisto abbastanza mirato. Il prezzo mi sembra adeguato per la funzione che svolge.

My situation may be a little bit unique but this Smof Ground Loop Noise Isolator is an absolute godsend. This completely eliminated all alternator noise I was getting through my car stereo.I own a 2005 Subaru Outback which didn't come with an aux in port and didn't have an easy way to add one. I considered replacing the stereo with an aftermarket unit until I found out the climate controls were integrated into the stereo and would cost a minimum of $250 just for aftermarket climate controls. I tried a few different FM modulators but struggled to find a station that consistently worked on my drive to and from work. As a last resort I found instructions online on how to hack my factory stereo and install my own aux port inline with the FM tuner. With nothing plugged into the port my FM radio plays; with a cable plugged in it plays from there. I spend a day modding the stereo and everything sounded fantastic while testing in my driveway. Later that day I started the car up and got my phone all hooked up only to be greeted by a horrible alternator whine screaming over my speakers every time I hit the gas.That is where the Smof Ground Loop Noise Isolator comes into play. I searched Amazon and based on the good reviews and price of the Smof I decided to give it a try. From the moment I plugged it in it has provided crystal clear audio. I now pair my phone to a bluetooth adapter which runs to the Smof then to my modded aux port. I have enjoyed hundreds of hours of audio books and music. The music playing from my phone through this setup provides significantly better audio quality than FM radio or CD. I could not be happier with this product and I'm so glad I decided to purchase it.

Did an exellent job with the humm and other intefering noises. I had a totally different situation than the most common use to an output to an stereo speakers. So you just have to try it.I was linking two radios for special emergency communication. This noise filter did the job.I was not concerned loosing any of the other frequencies. However, in my special situation it worked great.One of my laptops was generating a loud humming noise onto another. audio device, probably coming from the cooling fan. After I connected this filter, the humm was gone.It took it out instantly. The adapter took a little longer to arrive. Reason for the 4 stars.
