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

Tried two other similar products to eliminate buzz in my home theater subwoofer and neither worked at all. I have a long RCA running through the wall and ceiling from the amp to subwoofer that was already installed when I moved in. Doesn’t appear to be a shielded cable. Even the slightest increase on the subwoofer volume dial would produce a loud buzz basically making the subwoofer useless. This isolator made an enormous difference. Still a very slight buzz when I turn the volume up high, but at reasonable volume levels no noise at all. I can now use the subwoofer with pretty much no noticeable interference. Because this item has 3.5 mm input and output I had to use RCA adapters and the setup worked perfectly. Definitely recommend trying this product if you’re having a similar home audio problem.

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!

Just received. It removed the majority of the static, not all, but most. Also, it made my speakers a bit louder and increased bass in which I appreciate. Overall, I’m satisfied.

I bought this to deal with an annoying humming/whining noise coming through a 3.5mm audio connection. Installation couldn’t be much easier—just connect it inline between the audio source and the stereo. It made an immediate difference and reduced most of the background noise. However, in my setup I could still hear a faint amount of interference when the volume was turned up with nothing playing. I also noticed a slight change in the sound compared with connecting the cable directly, although it wasn’t significant enough to bother me during normal listening. For such a small and inexpensive device, it did a good job solving most of the problem without requiring any changes to the wiring. Just don’t expect it to magically fix every type of audio interference. Useful little adapter and worth keeping around, but because it didn’t completely eliminate the noise in my setup, I’m giving it 4 stars.

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.

Got this because my headphones plugged into my computer had so much feedback it was almost unusable. Putting this between my headphones and the computer resulted in a clean output. It works perfectly for this.

Bought an aftermarket carplay unit which could only be used with an auxiliary cable rather than bluetooth. There was interference with the pandora playing out the speakers. Both this noise isolator and it makes a huge difference. No more interference and the sound from the speakers is now great!

It worked to remove the buzing like sounds i would hear on my nova pros when i plugged in my razer audio mixer to my nova pro dac. Idk if it's how im now running my audio but seem like a very slight drop in over all audio loudness just enough if so for it to be questionable but like I said I am also running my audio differently to use the device regardless if it is or isn't its a 5 star for me

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!!!!
