Cable Matters 3.5mm Ground Loop Noise Isolator for Car Audio in Black

I have an old car, I bought one of those all in one dash cam carplay android auto dvr units, I tried using it with fm transmitter,meh,the bt worked but didn't connect automatically had to manually connect for audio,my phone too old, so tried the supplied aux cable and i got interference from engine, then did abit of research and came across this little device, wow its clear,just plug it inline on the aux cable, interference gone and everything thing connects automatically when turning car on and when engine is running, good to go.

I had my laptop connected to an AV amplifier unfortunately the wire was picking up EM interference from my wireless devices and even the fan in the laptop passing the noise through the AV Amplifier to my speakers spoiling the music I wanted to listen to. After fitting this device there is zero noise so I can hear music clearly. Excellent product. This will work on any stereo sound device using a 3.5mm jack plug.

This works perfectly for getting horrible ground loop noise out from my car Bluetooth adapter / 12v cigarette 12v port. Negative reviews must be user error as this was so simple 😂

Just got a new XLR setup for my gaming and streaming and this is a huge changer as I was dealing with a lot of electrical feedback from my second pc, definitely recommend this if you are running dual pc setup with XLR mics

Didn't work, still had buzz and wouldn't even pass the whole audio signal through. Waste of time.

No perceivable difference in sound quality in my car with the exception of it removing all the electrical system interference from the audio signal, job done. Install was simple and only had to include it on the aux in on the car radio, no external power required.

Don't waste your money* on chokes, transformers, removing earth connections, expensive cables etc. Just buy this and plug it in between your audio output and your speaker cable. For ease I didn't connect it to my computer, I just used the NVIDIA audio via the HDMI input to my monitor. Simply connected this to the headphone out on the monitor and that was it... ALL speaker noise & hum was instantly removed and the resulting sound quality is excellent! Highly recommended.. :-) *like I did

Bought a soundbar and the bar was making a buzzing noise, so thought this might work, but did not do the trick

Lo compré para nuestro coche, sustituyendo uno que se venía con el receptor bluetooth y que se perdió. El ruido se quitó de inmediato. Me gusta que no tenga un cable integrado, sino que tiene conectores en ambos extremos. Así, si el cable se daña o quiero usar uno distinto, puedo cambiarlo. Además, lo elegí porque el cable incluido tiene un conector en ángulo. Así queda prácticamente plano en el tablero del auto y es más difícil golpearlo.

Me hacía ruido el jak de la pantalla del coche y con el Filtro antirruidos, se acabó, buen sonido sin ruidos

werkt prima: in PC steken en dán je hoofdtelefoon of geluidssysteem.

Had very low expectation but it worked fantastically, got rid of all background noice!

Ground loop isolator... where has this thing been my whole life? Completely eliminated the annoying engine whine I was getting from charging my Bluetooth adapter while playing music. Clear audio at last!
