ZIOCOM Ground Loop Noise Isolator, Noise Filter (1 Pack)

I have two PCs and a PS4 connected to a mixer. One PC and the PS4 connect via my monitor's line out, the other PC connects via a USB powered Tascam Ministudio 42B. The noise this setup produced was, to say the least, annoying - constant crackling and popping, plus buzzing whenever a mouse was moved, especially aggravating at low levels or on headphones.So I decided enough was enough and consulted Gemini out of desperation, which immediately diagnosed a ground loop problem and suggested a device such as this. I didn't think it would solve it but, hey, at £9 it was worth a shot, right?It arrived and I plugged it into my monitor's line out, as Gemini had directed and took seconds, and turned on the PCs expecting to hear the same noises. The result? Blissful silence! Sure, if I turn the mixer inputs and outputs right up to where you'd deafen yourself if you played music there's the usual white noise you'd get from pretty much any consumer level analog mixer, but no crackling, no popping, no buzz when I moved a mouse! Audio from both PCs, not just the one routing through the monitor, was clean. I tried some music, and it sounded no different in quality than before, just cleaner in the quiet parts, so it's not affecting the dynamic range (at least not to my ears anyway)I wish I'd bought one of these years ago, absolutely superb results for virtually no money. Gemini also suggested a Behringer HD400 Hum Destroyer, to go between my Tascam Ministudio and the mixer. That's arriving Monday but I don't think I'll be needing it for my PC setup, so I'll be keeping that to use elsewhere.If you're getting similar crackling and buzzing from your setup don't even hesitate, give one of these little marvels a try!

Great product, cut out all feedback noise in my car

Worked perfectly to get rid of the buzzing sound I was hearing in my headphones. Well worth it

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.

Absolutely perfect, had alot of high pitched wine in the background when the volume was all the way up but using this got rid of it completely, well worth the moneyMy setup is a external carplay device using an aux plugged into the stereo

Item does work but affects sound quality too much for me to be able to use product. I'm not going to return because product does work, just very poorly.

Does it was it says I had interference through aux off carplay to stereo put this little device and nothing not a bit of interference lef

Awesome! This is just what I needed to tidy up the audio from my Uniden SDS200E radio when connecting its EXT Speaker jack to an audio mixer. Sounds much better now and without the big CLUNK noise when I turn the radio on!

Switch 2 と デスクトップPC のライン入力の間にかませてノイズをなくすために購入。想像以上にノイズがなくなってすごく助かってる。おすすめはするが、個体差あったらどんまい。あと入れ物がすごく簡素値段相応なのかコスト削減なのか。。

This ground loop noise isolator worked wonders for my home studio. After setting up a new ATEM Mini Pro ISO, I experienced a high-pitched whine through my mic lines. This affordable device completely eliminated the noise, saving me from having to buy more expensive cables. It is a high-quality, heavy-duty product that solved my problem perfectly.

Plugged it in to the TV. No more infuriating humming noise from the sound bar. Excellent device.

Works great for rid of the buzzing might order another

Very good. I use this together with a UGREEN Aux Bluetooth 6.0 Adapter and the sound is Crystal Clear.
