    • Absolutely excellent product! Small issue on Amazons side. Completely resolved.
It works absolutely great! Stunning difference! I used it to record audio from the headphone jack of a scanner to the line in of my computer with a dedicated software program. Prior to putting the device online I had a continuous oscillating tapping sound as well as extremely dirty audio that had a lot of hissing. Once this was installed inline, which was a simple plug it in on each end and done, the oscillating sound and all hissing and miscellaneous noise was gone and I’m left with pure, noise free audio recordings. I have to say that this was a second delivery after a lengthy delay with considerable excuses when contacting Amazon with my inquiries multiple times only to be promised it was on the way and given a new delivery date that came and went with no arrival of the product. Ultimately I was told it was lost and the service representative handled the return and reorder during the call and I was given another delivery date that was met. I don’t fault the seller in the least for this and had it not been lost in transit I feel the delivery would have been very quick as it was after the reorder. Excellent product and it honestly works better than expected and exceeded my expectations! ... show more

    • 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! ... show more

    • Problem solved! Works perfectly!
Rarely does something inexpensive do exactly what it's supposed to do like this. Without this, the engine noise was audible with my car stereo volume set at about 20 out of 60, now I can crank it to the max at 60 and it is still dead silent, and with no apparent effect on the quality/EQ of the audio coming out. Works perfectly. ... show more

    • Fixed noise using aux jack in vehicle
Works. Had a high pitch tone when using my CarPlay device plugged into the audio 3.5mm jack in my older truck. Clearly a ground loop. This took care of it.

The speakers still had some buzzing. But not as bad without it.

    • Fixed speaker buzz while treadmill running
I recently got an under desk treadmill, which is great, but had to turn my computer speakers off while the treadmill was in use because it caused a loud buzzing noise in the speakers. I purchased this ground loop noise isolator, plugged my speakers into it and then the isolator into my computer dock, and the buzzing is 100% gone. Great cheap fix! ... show more

    • Works Flawlessly
Was getting a noticeable, LOUD hum connecting a ChromeBox 3.5mm audio-out to L/R RCA plugs into an ancient Radio Shack audio receiver powering a couple of 100W stereo speakers for our home gym system. Connected this puppy up, and it was true plug-&-play - sound was crystal clear and noise-less.

    • Works great
As a truck driver I like to use my tablet to listen to my home radio station on the road. The problem was that charging the tablet made a lot of noise and humming. This completely eliminated the noise and seems to be made well as it holds up to the bouncing in the truck.
