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

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.

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.

Works as expected. Unwanted noise is gone completely. Connected PC to mixer using this. Recommend this product for SMPS based audio mixers and Power Amplifiers.

Filters the noise very effectively

This is an eye washing item. I bought this item to reduce "hum" noise from my microphone .... sorry to say that rather than reducing hum noise it reduced the microphone's sensitivity .. additionally distorts the sound quality ...

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.

It's resolved my issue. Now I am able to hear the music with out any electric noises

Does not work at all. My worst buy

Perfecto, funciona sin problemas.

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)

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.

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.
