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

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

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.

Did exactly what it said it would do. All ground noise gone!!

Totally removed a persistent whine from a set of old speakers connected to a Macbook and PC.

Bought this as I was running two Bose speakers from a headphone socket on a Sony TV and was getting static/noise when the TV was off (standby). Tried this and just made the static worse. Maybe works for Bluetooth/Car only, certainly doesn't work for my wired TV Speaker static.

Removes noise and doesn’t typically hinder sound quality. Quality of bass tones is poor when connected to the input of a computer though so I can not recommend it for that but for headphone output it works great

Ottimo isolatore antirumore.

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.

Works great for rid of the buzzing might order another

Gestern bestellt, heute bekommen. ich habe mir mit einem raspberry Pi einen PiCorePlayer mit einem kleinen Lautsprecher mit 3,5 mm Klinkenanschluss gebaut. Jedoch gab es häufig ein nervendes Brummen im Lautsprecher. Nachdem ich den Entstörfilter zwischen geschaltet habe, ist das Brummen weg und der Klang wie er sein soll.
