Ground Loop Noise Isolator for your Car Audio System/Home Stereo with 3.5mm Audio Cable[Eliminating Audio Hum Noise Completely] (Black)

I was really frustratred with the ground loop issue with my PC and studio monitors. Tried almost every suggestion mentioned on the internet forums, but no avail. The noise was making my high-end sound system absolutely useless. Some of the devices mentioned on the forums were quite expensive and yet did not promise 100% resolution of the issue. Then I came across a YouTube video that showed before and after results of Smof ground loop isolator. The noise before was exactly what I was experiencing and it was all gone once the device was hooked up. That video gave me enough confidence to buy this product. And now, my system is absolutely free of the noise!! There is no loss of sound quality either. I'm extremly happy with this purchase. Update: Almost one year has gone by and the sound from PC to monitors is still flawless. Great product. Highly recommended.

This little device saved me from a big hassle. I had high buzzing sound from my SVS subwoofer which I wasn't able to eliminate after multiple attempts. Noise disappeared after connecting this little device. It isolated ground loop as mentioned and it's much smaller than seen in the pic which is a boon.

This is working fine 95% but giving cracking noise with some audio file played.

Works as expected!! Slightly expensive but build quality and sound quality justify the price. I used it to remove buzzing/humming noise coming from my laptop speakers when connected to my LG Monitor (monitor has Audio Out/Headphone Jack). This generally happens when the device producing sound (in this case my monitor) and device emitting sound (in this case my laptop speakers) are connected to the same power source which creates ground loop. Now I can happily stream FireStick content on my LG Monitor without that annoying hum/buzz. I wish the price could be around ₹700 though since similar (slightly low quality) devices available at ₹500. Paying over ₹900 for this is expensive.

This product does not reduce the humming sound coming from external speaker connected with TV Headphone Port. Though initial delivery was Replacement category, I Thank both Amazon and Seller for their out of box kindness to approve Return and Amount Credit requests after first Replacement. 1⭐️ for Non functionality of the product. 5⭐️ for Return and Replacement Service of the product.

Good sound. After a while the sound kind of stops.

Filters the noise very effectively

I had kinivo b450 which was causing humming noise in my i10 OEM music system for which I bought smof. I had no issues till date and bluetooth music output is fabulous. I recommend it.

Perfecto, funciona sin problemas.

Funktioniert wie beschrieben. Ich hatte teilweise ein niederfrequentes Brummen und Rauschen in den Lautsprechern die an einen kleinen Htpc im Wohnzimmer angeschlossen sind. Der Grund dafür sind Elektromagnetische Störungen die vom Pc bzw. dem Netzteil über die Erdung Rückübertragen werden. Genau dem wirkt der Entsörfilter entgegen und das zu 100% in meinem Fall. Keine Störgeräusche und Rauschen mehr ohne negative Auswirkungen auf das Ausgangssignal.

Problema solucionado ✅️, tenía el típico zumbido en los altavoces, el sistema era un radio y un míni amplificador de 2+1,la verdad que no confiaba mucho en el filtro pero me sorprendió mucho, ahora el sonido está muy bueno y limpio de parásitos, genial recomiendo mucho,quiero añadir también una cosa la calidad del cable rca es muy importante los típicos cables chinos rca te van a dar mucho dolor de cabeza, los mejores son los que vienes con las puntas bañadas en oro y empantallados (bien aislados)

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.

Ho collegato Echo Input in auto: col bluetooth nessun problema, ma con cavo aux partivano una serie di fruscii in sottofondo abbastanza sgradevoli. Da quello che ho capito questo fenomeno prende il nome di ground loop: se colleghi con cavo aux un apparecchio che si alimenta dalla stessa fonte (nel mio caso aux in autoradio e alimentazione usb in autoradio), avrai dei rumori di fondo, come i fruscii emessi dalla puntina di un giradischi. Infatti, se avete lo stesso problema, collegate il telefono all'aux dell'autoradio e alimentato a batteria e vedrete che non avrete problemi. Il problema è sparito collegando questo dispositivo. Personalmente non ha abbassato il suono in uscita quindi lo trovo perfetto.
