BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable

I recently purchased the UGREEN USB Audio Adapter to solve an issue I was having with noise in my docked computer speakers setup for my MacBook Pro. This little device worked like a charm and completely eliminated the annoying static and interference that was plaguing my sound system. Instant Noise Reduction The main reason I bought this adapter was to address the persistent noise that I would hear through my speakers when my MacBook was docked. It didn’t matter what I was doing—whether listening to music or joining a Zoom call—the interference was always present. As soon as I connected the UGREEN adapter, the difference was immediate. The noise disappeared completely, leaving me with crisp, clean sound. Easy Setup and Plug-and-Play The setup couldn’t have been easier. It’s truly plug-and-play—just plug it into the USB port, connect the speakers or headphones, and you’re good to go. There were no drivers to install or any complicated setup process. Within seconds, the audio quality improved dramatically. This was a simple, effective solution to a frustrating problem. Compact and Convenient Design The adapter itself is small and sleek, which is great because it doesn’t add any bulk to my setup. It’s easy to toss in a bag if I need to move around, and its design feels durable. Despite its compact size, it packs a punch in terms of performance. Great for Multiple Devices While I mainly use it with my MacBook Pro, I’ve also tested the adapter on other devices, including a Windows laptop and a desktop, and it worked just as effectively. The versatility of this adapter is a bonus, as it can solve audio issues across various platforms. Affordable and Effective Solution Given its affordable price point, the UGREEN USB Audio Adapter is an excellent value for what it offers. If you’re dealing with audio issues related to interference or static in your speakers, this is a quick and reliable fix without breaking the bank. Final Thoughts Overall, I’m extremely pleased with this purchase. The UGREEN USB Audio Adapter solved my noise issue perfectly, and the sound quality has been significantly improved on my docked MacBook Pro setup. It’s a must-have for anyone experiencing similar problems with audio interference. Highly recommended!

Amazing! Old PC speakers died and I got tired of buying them. So I stepped up to monitors but soon realized I had noise. Tried choke coils thinking my video card was bleeding into them. Nope ground loop. And room is all ran on one breaker so I was stuck. This gadget killed ALL noise. I can crank my speakers listening to music with ZERO noise. Play games (where they noise really was pronounced) undisturbed!

Easy plug-and-play, and it does an excellent job of removing noise interference. Volume does decrease a little, but it's an expected trade-off for no unwanted humming

This thing does exactly what it says it does. The fat little section has an inductor that creates the magnetic field that makes sure when current (sound in this case) flows through it, it is normalized and doesn't have any potential difference (which causes the hum we all hate). It's cheap and works on the 3.5MM input that I plugged it into and no matter how much power I throw at it now, there is no more hum. A good buy and I recommend. Pro-tip: Where do I put this thing in the sequence? The age old question of before or after that amp??? Well, conventional wisdom usually says add this inline as close to the amp as possible between the head (stereo) and amp. In other words, put this on the input side of the amp. Stereo --> Isolator --> Amp --> Speakers. This works in the vast majority of cases. There are some instances where there might be components after the amp besides the speakers, perhaps some kind of Bluetooth adapter, or game console, or something. This situation is more rare but in that case you'd put an isolator after the amp (out put side) but as close to the speakers as possible so Stereo --> Amp --> Component X ---> Isolator --> Speakers. There is also a third scenario where you put an isolator before the amp AND after the amp but before the speakers because you are getting two kinds of issues like potential current differences from a bad ground on the stereo feeding into the amp (corrected with the input side isolator) and then a shielding problem on the way to the speakers or another component that is leaking on to the line with a bad ground or the like (corrected with the output side isolator closest to the speakers). Why not just add one single isolator as close to the speakers as possible to correct it all? I'm glad you asked. This is because unless you get super high quality and usually powered isolators, you can't expect miracles and the potential difference might get so high that one isolator just isn't enough to correct it all so you correct it one step at a time after each component that is causing an issue. Bottom-line: One isolator on the input side of the amp or right before the speakers is usually enough and this thing works great for that.

It made the audio going into my headphones extremely quiet, though it did contribute to fixing the problem I had with ground loop noise.

It works. So I'm using this between headphones and an old amp. The amp generates a fair amount of ac hum that was becoming annoying. This little device has cut the hum way down and even helped with the popping I get when the hvac kicks on and off. But unfortunately it also lowers the overall volume, so I have to increase my source volume. It's not perfect, but does the job well enough to keep around. Overall I'm satisfied with it.

It worked to remove the ground loop noise or buzz from connecting one computers "speaker out" to another computers "line in or mic in" and turning on listen on the second computer. Easy to setup, use, cost was amazing.

Did exactly what it was described to do. I was setting up a new digital mixer for our church and the PC output was causing a lot of noise. I inserted this between the PC and the output and the noise instantly stopped. There does not appear to be any sound degradation.

Very effective for my car made my speakers sound amazing I'm autally stunned how good this thing is.

Ich habe dieses Gerät erworben, um eine deutliche Brummschleife zu beseitigen, die in meinem Wohnmobil durch den Wechselrichter verursacht wurde. Die Audioquelle ist mein Fernseher, dessen Ton ich über das Radio ausgeben lasse. Solange der Wechselrichter aktiv war, war das Brummen ausgesprochen störend und machte den Musikgenuss unmöglich. Nach dem Einschleifen dieses kleinen Geräts über die 3,5-mm-Klinkenverbindung wurde das Brummen vollständig eliminiert. Der Ton ist seither glasklar – das Ergebnis hat mich sofort überzeugt. Zur Langlebigkeit kann ich zum jetzigen Zeitpunkt noch keine Aussage treffen, da ich das Gerät erst kürzlich in Betrieb genommen habe. Der erste Eindruck ist jedoch durchweg positiv, weshalb ich derzeit 5 Sterne vergebe.

Este pequeño y barato dispositivo solucionó un problema de ruido bien gacho que tenia al tratar de meter una linea de audio a la computadora, ya que esta hacia "reaccion" con la tarjeta capturadora debido a la configuracion que tengo. En fin, se escuchaba un ruido muy fuerte y molesto, no solo eco o un zumbido leve por lo que tenia mis dudas pero por el precio decidi arriesgarme (al ser de importacion es mas relajo la devolucion) y resolvio mi problema al 100% eliminando el ruido por completo. Es pequeño y viene bien empacado, se ve y se siente de calidad a pesar del precio. Lo recomiendo sin duda si tienes un problema similar.

Bastante mejor de lo esperado, en mi caso se ha eliminado el zumbido por completo y no ha perdido volumen la música, lo recomiendo sin duda

Werkt uitstekend inbde auto. De ground loop ruis verdween als sneeuw in de zon. Stond versteld van de kwaliteit. Echte aanrader voor diegenen denken dat de ruis door de ground loop komt.
