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

Surprisingly does the job. Use it for my switch 2 to computer speakers that all are connected to power amp/dac. Before, the switch 2 dock generates a terrible buzzing noise but with this it completely gets rid of it. I did have to turn the volume up a little on the amp but great trade off. The switch 2 dock is dogpoop and has no audio shielding soooo just heads up.

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!

I bought two of these. I had two different sound issues and they were both resolved by this ground loop noise isolator. One was used with a work laptop. The 1/8" audio cable from the laptop to my mixer was the first place I used it. It immediately resolved my issues. The 2nd isolator was plugged into my gaming pc that runs into a mixer. It had low level static. This fixed the issue completely. Highly recommended!

Noticeable difference. Purchased this to correct the audio I was receiving from my audio amplifier. It worked, no longer hear a white noise in my audio. It is sleek and works. Noticed it worked better by putting it closer to the earpiece than closer to the audio source. Recommend this to anyone as it does make your audio sound better and hearing is one of the five great human senses.

Works as advertised. Completely eliminated the white/ground loop static noise coming from audio out of a fairly cheap ($20) mixer :) I ended up returning this one though, for another ground loop noise isolator with a shorter cable, since both isolators worked identically from what I could tell.

Bought to use with a Cardo Spirit communicator with Shure 215 IEMs. There is a very noticeable hiss when the communicator is actively transmitting audio that is likely negligible with the included speakers, but is evident with greater sound isolation and quality. This noise isolator greatly reduced the hiss, to be effectively inaudible when audio is playing. Would recommend for similar use cases. Great price, but a little bulky on a helmet for motorsports/atv/etc.

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.

Immediately after it was plugged in, the noise went away

Works!!

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.

Cet objet est tout à fait excellent. Je stream sur la plate-forme Twitch (adrishh), j’utilise une table « son » de la marque GOXLR pour relier mes deux PC en son (mon pc principal est mon pc qui est chargé de récupérer mon flux plus vidéo). Je n’ai eu aucun problème pendant un an. Jusqu’au jour où un viewer m’indiquer pendant ma pause café (moment où il y avait aucun bruit) qu’il y avait un bruit vraiment désagréable. J’utilisais des câble, jack 3,5 mm mal mal basique pour faire le raccord Line in / Line out. Je les ai donc changé et je suis passé sur les cables blindé. J’ai donc accoupler ces deux cables a l’isolateur des bruit. J’en ai acheté deux (isolateur de bruit), un que j’ai appliqué à l’entrée Line in de ma GOXLR, puis le second a l’entre Line out de mon PC de stream. Quand j’ai testé avec un seul isolateur de bruit sur l’entrée Line in de ma GOXLR ça réduisez déjà à 95 % le bruit! Mais en appliquant un deuxième isolateur de bruit sur l’entrée Line out de mon pc de stream, alors ça éliminer 100 % du bruit entendu. Voilà les streamers, en espérant vous avoir aidé. Enjoy

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.

ha eliminato tutti i fruscii tra l'uscita audio del pc e le casse audio!!!! ottimo!!!!
