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

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!

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!

My GTi is old - it's model year seems to have been the last one prior to the widespread introduction of usb ports as a standard piece of kit for new cars by VW. It has several buttons for satellite radio and a DVD-based navigation system. Bluetooth audio was moving from a rumor to reality but still a few years from being available as a feature. So no easy wireless audio existed for me in this car - only an aftermarked aux jack that I had been plugging into via Apple's Lightning to 3.5mm adapter. I tried using a Bluetooth dongle, which brought brief joy followed by the realization that it would need frequent charging, which invariably brought on the eerie, disembodied, hissing menace of the Audio Ground Loop. Efffff. BUT - I love my GTi; it's paid off, cheap to insure, and driving it still puts a smile on my face. Two weeks ago I did a bit of research on reliable isolation devices, got overwhelmed by the crushing weight of paid-for, AI-faked, ludicrously off-topic, and real reviews, and decided to just buy the most popular one on the big A. Thing works great. No degradation in quality (to my somewhat practiced ears), nor any decrease in volume. Just plugged my bluetooth receiver dongle into the cigarette lighter outlet/usb charger, connected this thing's built-in 3.5mm male cord to the dongle's output, then ran a short 3,5mm cord from this isolator to the aux jack. Voilà. Now that setup sits, out of eyesight, in the emergency-brake-lever area to the right of the driver. When I start the car, on comes the bluetooth. With this isolator in place, I have seamless, interference-free bluetooth audio from my iphone without ever having to plug the phone in to anything. Wonderful. Writing this review was harder than setting it all up.

Très surprenant ce petit filtre. Filtré complètement le retour dans les hauts parleurs dus à une boucle de masse… assez impressionnant pour le prix et la taille. Un impératif dans une installation auto avec connection jack.

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.

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.
