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

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.

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.

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 took almost all the hiss out of my signal chain. Unless you are recording with it, most people will find this suitable. Easy connection. Versatile, I used it before the aux in on my mixer, and the phones out.

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!

This is an excellent product (Ground Loop Noise Isolator) to use if you have any type of device that has unwanted sounds in the audio, such as a hum, or buzz, or stray radio signals. I bought two of these, one to plug into a TV sound bar (which had this horrible hum or buzz that started growing louder each time after I turned the sound bar on, and this device immediately fixed the problem perfectly as soon as I pugged it in to the audio line between the TV and the sound bar.. I plugged the second one that I bought into an audio cord coming out of my desktop computer that goes to computer speakers. These speakers had a hum in them, but they also picked up soft talking that sounded like it was coming from a far away radio station. This immediately got rid of all of that unwanted noise and interference, resulting in the excellent, clean sound quality that I wanted. I highly recommend these. I had tried all kinds of other things in an attempt to get rid of those audio noise problems, with no luck in the past. But this device fixed it quickly, and it was inexpensive, and extremely easy to connect.

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

I was having static and hissing issues using my computer speakers and this fixed the issue 100%

Works!!

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.

Une libération pour moi. Petit appareil qui ne prend pas de place et fait son taff à la perfection. J'avais à la fois un retour de bruit blanc dans le casque, mais surtout les personnes in game m'entendaient avec un bruit d'essain d'abeilles en fond ce qui n'était pas du tout agréable pour eux. J'ai ai acheté 2 pour m'assurer d'éliminer à 100 % le bruit ce qui a parfaitement fonctionné. Je suis plus que ravie et remercie les autres commentaires qui m'ont justement aider dans mon choix et m'ont rassurer à l'achat de cet appareil.
