DSD TECH SH-G01L USB Isolator Supports USB 2.0 480Mbps High Speed Isolation

The USB Isolator worked as expected.I bought this because I installed an Android radio that had Apple CarPlay on a 2016 Mercedes Benz E350 with a NTG5 unit. The car stereo does not have an Aux Port nor the Media Interface, the car connects to my phone via bluetooth or using the USB connector inside the center console USB1 or USB2. The Android unit I bought needed to connect to either USB1 or USB2 inside the console with a converter coming out of the Android Unit with the Red and White (L and R audio) converting to an AUX tip. This AUX tip connected to another converter from AUX to USB, in order to get sound to the factory car stereo. I got sound, but it has this loud humming/buzzing sound. I initially thought I should buy the AUX Isolator, but after disconnecting the the AUX tip from the AUX to USB converter, the humming/buzzing sound was still present. That's how I knew I needed a USB isolator. Hope this tip works for anyone adding an Android head unit to their car.

I was struggling with GPU / CPU noise through the headphone jack on my M-Audio Air 192|6. Oddly, it was only through the headphones, but not through the mains. I tried a few different solutions... An adapter to eliminate the ground lug on the plug... Buying a large power strip and running all PC & audio components through it... Placing ferrite rings on the USB cable... Nothing worked.However, this USB isolator did the trick. The annoying humming/buzzing is gone. I assume the problem was from poor shielding on the PC motherboard, but whatever the case, I am thrilled to finally have a solution to this annoying issue!

I've been fighting USB ground problems between my new computer and guitar for many months. I got to a point where it was solved then changed the configuration for other reasons and the problem returned. I'd tried USB isolators before and they didn't work. This one did - in my configuration. I'm using it on a guitar processor that's not directly in the computer's audio path. USB from the computer to that processor is only used for control. Nevertheless, this little dongle solved the ground problem. I'm stoked!

I have a DAW home recording studio with multiple components that have been recently purchased and was having noise issues on the monitor speakers. I'm using a Focusrite Scarlett 18i20 DAC, Presonus Faderport 16 controller, Sansui 27 inch WQHD monitor and a GMKtec mini computer. Noise was audible and fluctuated when using the mouse and keyboard navigating on the computer. This is generally a "ground loop" issue especially since my audio monitor cables are balanced. If you are experiencing a noise that is monotone it may be simply a faulty cord or power adapter and not a ground loop. Unplug each component one at a time to isolated the noise source. The ground wires in your home do not carry active house current and is a secondary protection in case of electrical shortages that will allow current back to the panel to trip a circuit breaker instead of a person being in series with a circuit in the event of an electrical anomaly. However unwanted magnetic fields with a wire nearby (such as a ground wire) produces signal currents that may interfere with devices sharing a circuit. Fan motors such as on computers may generate magnetic noise in this fashion.On my system when plugging and unplugging the USB cord from computer to DAC, noise would follow accordingly. After installing the DSD TECH USB isolator at 480MBS it worked like a charm and eliminated GL noise. I like the mini length cord since it allows room to plug in at the device with tight spaces sharing USB ports unlike the other more expensive bulky non-corded isolators. Also its reasonably priced comparatively and does NOT need a secondary power source to operate. I do not usually review products but wanted to post my experience to help anyone who has audio equipment noise issues and has been perplexed to find a solution. I highly recommend this product for ground loop issues for USB 2.0!!

Tried everything - from expensive RME and Steinberg audio interfaces to a cheap ancient usb audio card circa 2010. "Windows cannot recognize your USB device". While the "isolator" is alive - at least red led light in it, which probably means: "I'm isolating you from your USB port functionality".Worst purchase of the year.

GREATLY reduced the static audio interference generated by my USB mouse.

Worked for me!
