🔇 BESIGN Ground Loop Noise Isolator: Enhance Audio Quality in Your Car or Home Stereo System with 3.5mm Audio Cable Review

I had a problem in my car where I couldn't plug the auxiliary cable and charging cable into the cigarette lighter at the same time. This creates a lot of static noise. I read that they eliminate this noise. I plugged it in and haven't had any problems since. Well worth the already low price!

Works very well overall. I have ground loop noise or RFI at the source which I can't currently fix which drives me crazy at times. I connected one of these to the input of my mixer and the noise was significantly reduced. Unfortunately not zero. I put it on the mixer output and nothing comes out. Completely gone. However, there is a caveat. Low frequencies are mostly fine, but really low frequencies sound harsh, and something like an exceptionally low bass kick can end up severely clipping and…

2006 Mercedes C230 - I installed an extra connector via a Mercedes OEM cable. When you plug the phone into that aux port, the sound is great. I then plugged a $10 USB Bluetooth adapter into that aux port and the sound was awful with a lot of hissing and crackling which wasn't acceptable so I accidentally found this when looking for a new Bluetooth adapter have searched. As instructed I connected this isolator to the Aux port and then the 3.5mm MM cable from this isolator device to the bluetooth

I built a portable bluetooth speaker that works with a 12" plug. Everything worked fine except for the digital noise at low volume. I traced this to a bluetooth dongle that needed power and ties signal ground together via the power amp RCA jacks and pushes the bias through the A/D converter amp It was in the key so the filter capacitor was useless on the power side The BESIGN Ground Loop Noise Isolator does exactly what its name suggests and isolates the key output from the amp's ground. This…

I was having noise in my headphones while gaming on the computer. While researching this I found out that it is some kind of electrical interference caused by the graphics card or power supply which increases the power consumption to run the game. The recommended solutions were an external DAC, a sound card or this device. I first tried a sound card that didn't eliminate the noise, and then I tried this one. This device completely removed the buzz in the headphones during gameplay. I am very…

UPDATE (1+ years) Used 2 of these in my virtual pinball game and they work great. Now that I'm working from home, I'm listening to music on my new work laptop. Unfortunately, the outlet in our old house isn't properly grounded and I just don't have the time or energy to fix it. And so I get the classic 60 Hz hum. But NOT with this product! So I'm going to buy a third one for my office. ---------- Day 1 of use but so far I am very satisfied. I'm creating a virtual pinball game that involves…

These things are perfect. The quality is fantastic, there is no electrical contact from side to side. They eliminate 100% ground loops or other electrical signal interference. They do not affect the sound quality. They work by sending a signal through a transformer. Actually one per channel. The transformer is symmetrical. That is, the input winding is identical to the output winding. This means that even though the device doesn't have a conductive path or any form of electrical connection, the

I had two issues I needed to fix. These ground loop isolators solved both problems. I used to try buying different audio cables, plugging computers into different power adapters, different AC outlets, rearranging all the power cords, USB, ethernet and other cables and I still had a noise and hum issue. The first issue I got from my Arctis Pro wireless headset was static. (This model's wireless functionality is controlled by a USB base station that connects to my PC for power and then to my…
