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

I bought this noise loop isolator to fix the static/humming sound in my headset, and it actually worked right away. Before using it, I had constant static and buzzing, especially when connected to my PC. As soon as I plugged this in, the noise was gone. Audio sounds clean now with no interference. Super easy to set up — just plug it in and it works. No extra settings or software needed. Build quality feels solid for the price, and it’s small enough to not get in the way. If you’re dealing with annoying static or ground loop noise, this is definitely worth it. Fixed my problem instantly.

Using this with my MacBook Pro and external computer speakers. Prior to using this, if I had the speakers volume control turned up past about 1/3 volume, I would get a pretty noticable hum through the speakers. It was there when music was playing or not. I learned about Ground Loop Noise Isolators and figured for under $20, let's give it a shot. It works great! I actually have it inline between my computer and a KVM switch I use between two machines. It works perfectly eliminating that low hum that was present. I can turn the volume knob to full and the hum never shows up!

Works as intended! I recently bought a new gaming computer and when I hooked up my speakers/sub to my amp and connected it to my computer there was noise coming from the sub. This device plugs right in and took care of the problem! Now my system is crystal clear with deep bass for those long gaming sessions!

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.

I installed an iPod Nano (1G) dock in my truck 20+ years ago. I wired the dock directly to the cigarette lighter circuit (it was a 12V automotive dock. This worked fine with my Blaupunkt CD player, which had rear RCA inputs. I replaced that head unit with a cheapie Jensen Bluetooth deck, which has a front headphone jack. With this (much cheaper) head unit there was a high pitched dirty wail on the AUX input, which was very noticeable when the volume is turned up. This little noise isolator completely eliminated that noise. Gone. I was skeptical that this could even work, and then when reading the directions I also realized it was supposed to be hooked up opposite of my setup (male to stereo female to ipod). So I figured it wouldn't work well or at all. WRONG. The noise is completely gone, and now I don't have to pull the dash apart again to wire in a power filter. 100% recommend this, it saved me probably 3 hours of work in a hot car with no AC in the NC springtime. Highly recommend.

Great device and it works well. The noise went away immediately! Very satisfied!

I had a hum from associated with my speaker hooked up to my computer, specifically the sub woofer. I unplugged speaker lead from the back of my computer, plugged it into the isolator then plugged the isolator where the speaker was , no more hum. Though when I turned off computer there was a hum in the speaker, so I just hit the off button on the speaker

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.

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.

Tengo una televisión y una barra Sony al que puedes conectar para que el altavoz de la tele haga de altavoz central, pero no lo usaba porque se escuchaba mucho ruido estático, con este aparato ha desaparecido el ruido.

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.
