ZIOCOM Ground Loop Noise Isolator, Noise Filter, Eliminate the Buzzing Noise for Car Audio/Home Stereo System with 3.5mm Audio Cable

I was very sceptical of this product as there are tons of fake ones being sold online. I was positively surprised, as it removed the buzz I was getting from my GPU to my active studio monitors. The jack to jack cable could be a bit better, but it does the job really well. I can't discern any noticeable bass attenuation either, so happy days! Highly recommeded

This thing saved my sanity. The almost inaudible but intensely annoying constant whistling noise from my speakers (regardless of whether they were in use or not) has now gone. Great!

As someone who spends a lot of time fine-tuning my car audio and home stereo systems, I was increasingly frustrated by the persistent humming and buzzing that seemed impossible to eliminate, until I came across the ZIOCOM Ground Loop Noise Isolator. From the moment I connected it between my phone and AUX input, the difference was immediate. The annoying buzz that had been interfering with my music completely vanished. Whether I was using it in my car or connecting to my home speaker setup, this little device worked flawlessly. It’s truly plug-and-play, no need for software, no complicated installation. What I love: ✅ Instant noise elimination: No more ground loop interference or static hum. ✅ Compact & portable: It fits neatly in my glove compartment or audio drawer. ✅ Quality build: The cable and housing feel durable and well-made, not flimsy like some cheaper alternatives. ✅ Universal compatibility: Works great with everything from my iPhone (via adapter) to my tablet, stereo receiver, and even older MP3 players. What could be improved: 🔋 It would be nice to have a slightly longer cable version for more flexibility in tighter setups, but that’s a very minor point. Pro tip: Use it between your Bluetooth receiver and car stereo if you're experiencing background noise during calls or music playback, this completely solves it. Overall, ZIOCOM has delivered a reliable, affordable solution to a common problem that plagues many audio systems. I wouldn’t hesitate to recommend this to any audiophile, casual listener, or tech-savvy car owner.

Works just as expected. Managed to get rid of interference to my amp.

Connected my Avtex TV through the headphone 3.5mm socket to my Kenwood head unit in my motorhome. I wanted the TV sound to use the motorhome sound system. It worked but had an annoying background humming noise. Googled the problem and it came up with this piece of kit as a fix. At £8.99 I tried it. Worked a treat. No more humming and I can use the equaliser on the Kenwood to set a superb sound especially when watching movies. I highly recommend this simple piece of kit.

Just bought a CarPlay/Android Auto device to hook up to the Transit and the buzzing through the speakers was nothing short of awful. After a bit of research I discovered this. I really didn't believe it would work. I have no idea what manner of magic is inside this thing, but the difference is astonishing. Just plug it in to your aux/line out and play. Words don't do it justice, so have a look at the video. But don't have the volume up too loud because the electronic hiss/buzz/noise is loud initially.

did absolutely nothing to eliminate feedback noise (laptop 3.5 phono/external speakers

I was pleasantly surprised that this little gadget stopped the interference on my CarPlay device, however, the jack socket is not reliable and I have to make sure the lead is not pushed in too far. If it is, the sound is muffled and quiet. I did think about returning it but it seems to be ok providing it doesn’t get knocked or moved.

Açıkcası işe yarıyor mu emin değilim. Ama gürültü problemini biraz çözüyor. Ama gürültünün kaynağı başka ise çözmez. Yani ona göre alın. Eğer yer döngüsü kaynaklı gürültü varsa iş görüyor. Ama adaptör yada başka bir şey kaynaklı ise işiniz görmez.

Worked great! Fixed the static sound I was getting from adding my gaming monitor audio to the line in on my PC so I could hear the game audio through my PC headset and it worked! but I was getting some moderate static noise which this solved!

Al conectar el audio del teléfono en el coche mientras estaba cargando, se colaba una especie de ruido aleatorio bastante evidente por los altavoces, sobre todo en los momentos de silencio. Poniendo este filtro por el medio, el ruido desapareció totalmente, sin perder potencia ni calidad de señal. 100% recomendable.

Bought this as a last ditch effort to fix a noisy PC - the noise I was getting was from moving the mouse or scrolling with the mouse wheel, and in some websites and PC games there was a constant electronic buzz and/or whine. I plugged this device into the stereo output on the back of the PC using the included patch cable, plugged the box to that and my PC speaker cable to the box. Problem solved, no software, no power, no batteries needed and speakers are dead quiet now. Also, I did not notice any decrease in volume or loss of treble/bass. I do not know if it will work for everyone, but it worked for me.

Habe das Teil jetzt zwischen Verstärker (Kopfhörer-Ausgang) und Equalizer hängen. Kein rauschen mehr was über Kopfhörer noch zu hören war. Die Chain ist wie folgt: - Onkyo C-7030 CD-Player am Chinch hinten ..... - ..... via Chinch an den Verstärker Pioneer A-505R 100x100 W ..... - Beide Geräte hängen nah zusammen an einer Steckdose. - Weiter weg an derselben Steckdose quasi hängt der Equalizer und PC-Aktivboxen. - So, weiter in der Chain: - Vom Pioneer Verstärker geht es über Kopfhörer-Ausgang ..... - ..... über ZIOCOM Entstörfilter (dort hat an- und abstecken vorher massive Audio-Kracher!! verursacht) ..... - ..... über relativ langes Audio-Chinchkabel ..... - ..... an den Pioneer 7-Band GR-555 Equalizer (hinterer Eingang, Chinch) ..... - ..... von dort dann ebenfalls via Chinch .... - ..... an Aktivboxen von Creative (T30 Wireless) Fazit: Die Störgeräusche sind passé und bei an- und abstecken gibt es auch !!KEINE!! heftigen Spannungsspitzen mehr, die für extremes lautes Störgeräusch in den Boxen (Maximalbelastung) früher sorgten. Das Teil ist also absolut sein Geld wert. Auch mit angeschlossenen relativ qualitativen Over-Ear Kopfhörern ist kein Pegelrauschen mehr vom Stromnetz (bzw. Verstärker) wahrnehmbar. Der Sound ist fantastisch und klingt natürlich, was wohl auch am Onkyo CD-Player (C-7030) mit dem VLSC Schaltkreis liegen könnte der für detailgetreue Wiedergabe (durch den Wolfson 192 kHz/24 Bit-DA Wandler) sorgt. Vom Player gibt es übrigens auch eine Variante mit MP3-Anschluss! Klare Kaufempfehlung für den ZIO. Viele Grüße und hoffe es ist hilfreich für Euch. Liebe Güße M.
