Review: Simple , Inexpensive and works 100% - 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!
Review: Impressive Noise Reduction for My Docked Setup - 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!

## Questions & Answers

**Q: Does this have the ability to also have the microphone pass through this device? I would like to use it with a microphone headset.**
A: Thanks for your inquiry, this ground loop noise isolator is not workable for the microphone.
Any further assistance, you could contact us via e-mail: bdesign-us@outlook.com.
Thanks.

**Q: can i use this on my raspberry pi arcade im runing sound thru audio to 5.1 pc spekers setup will this stop hiss on speakers?**
A: Depending on your setup, no. It will strip low-end signal entirely and affect the audio negatively: I tried on a PC 5.1 system (on the stereo pair 3.5mm main pair) and it stripped all the low-end frequencies.

**Q: Will this work with 250ohm headphones hooked up to a gloxlr mixer?**
A: Yes. you won't run the headphones into this though. You can find videos online on how to properly use but You'l want to connect this to your PC/ Go XLR depnding on the in/output causing the noise.

**Q: I have a Amplifier and a dsp like a eq but digital I get humming and buzzing noises where do I plug these in?????**
A: I’ve got mine plugged in to the aux on my car stereo, which is also the amp, so my best guess in your case would be to plug this into your amp, and then plug your DSP device into this noise isolator. Your may be different, course, as yours is a different setup, but you could always test it at the various connection points. It definitely works in my car, though.

### ⭐⭐⭐⭐⭐ How to get rid of the hum! Plus a pro-tip
*by C***C on April 12, 2024*

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.
