Details
Single USB to USB Port Isolator
Medical and Industrial Application USB to USB Single Port Isolator up to High Speed 480Mbps. USB isolator is USB bus powered and can provide 5V 320mA to your USB device with built-in isolated DC to DC converter. This is possible when the isolator is connected to a high power USB host port. A power supply is available and sold separately for this Isolator.
USB Isolator protects your PC or Laptop while connecting USB peripherals which is wired to high voltages. This small, industrial - grade isolator is very easy for use and provides a high-voltage barrier for protection against surges, noise and ground loop errors. It is suitable for use in sensitive applications like automotive measurements.
The isolation protects equipment from electrical over-voltages and transient voltage spikes. By eliminates ground loop currents flowing between the PC and USB device which can cause damage and inaccurate measurements. Additionally, isolation minimizes conducted noise from static discharge, magnetic fields and radio frequency interference.

This will work if hooked up correctly
Review by
Troy King
I have a small studio in my home and have some grounding issues with my high gain amps I seem to get a microphonic issue using my guitar effects pedal board. I tried and replaced everything I could to fix, and nothing helps. So, with that I removed the pedal board and started using my fractal fm9 mkII turbo and that solved the microphonic issue but created another issue. When the fm9 is hooked up by usb to my computer I get a ground loop noise. So, I ordered one of these usb filters and it failed to work so I sent it back. 3 weeks later I ordered this one and it worked no more noise. I see some say it is junk, but I can say it is not, it worked for me. My setup I use an ampete amp/cab/effects loop switching system that allows me to switch amps and cabs at the push of a button and the effects loop on all the amps share the fm9 when selected.

It solved the problem
Review by
Seth
I was getting background electrical noise in my headset. It wouldn’t show up on recordings, but it was annoying and distracting when I recorded. This unit is not cheap, but it solved the problem 100%.

Fixed audio interface interference
Review by
Josh
Had a terrible hissing and static sound coming through my Focusrite Scarlett Solo audio interface. Tried balanced TRS cables first which did get rid of most of it, but could still hear feedback from the monitor and mouse movement. Plugged in this isolator and the remaining sound was immediately gone.

Would be 5 stars if supplied with the power canle
Review by
Rachel Lake
Immediately solved an electrical noise issue on the USB. The product does not come with the 5V power supply not even a USB cable to use with a typical 5V USB wall charger. That said, I had moved my home recording studio and was experiencing significant noise to my Focusrite audio interface; both genral static and noise related to disk access, usb mouse movement, GPU processing, etc. this unit instantly solved that issue.

Worked for my digital piano and DAW
Review by
Sparky
I have a home digital piano and a computer that hosts Digital Audio Workstation (DAW) software. The piano has a two prong plug (i.e., it has no ground). It has a USB connection to the computer for MIDI and PCM audio streams. And it has line outs that I wanted to connect to my studio monitor speakers. The computer also has line outs to those studio monitors. That makes two paths to the computer Earth (house power) ground from the piano (USB and speaker line outs) forming a classic ground loop. The result was noise in the speakers. Isolating the ground on the USB connection eliminated the noise completely.
This device is "plug and play". It took all of about 1 minute to solve my problem.

Works well enough
Review by
Roy Mustang
It doesn't completely block out the static/hum since I can still hear it if I turn my amplifier way up, but it works well enough since listening at those volumes is harmful anyway. The first one I received was open and didn't work despite ordering new, I ordered a 2nd one and that one worked.

Got rid of my coil whine.
Review by
Nathaniel McAllister
As the title states, I have been liquid cooling my graphics cards for years and they all have one thing in common, coil whine. Some of the cards have been worse than others, looking at you 1060 but all have been bad. I recently got a EVGA 2080 TI and no I am not bragging. With the regular heatsink the coil whine was noticeable but not as bad as the 1060. Once I put the water block on it though, it was worse somehow. I have tried running a Schitt Asgard DAC thinking since the sound card is not in the case it will get rid of it and it didn't. I pretty much gave up on getting rid of it until I watched a video from PSaudio that was made last week. He stated to get rid of ground loop use a USB isolator now obviously, that's not my problem but I figured I would give it a shot. I am glad I did it completely got rid of the coil whine on my speakers that are connected to my DAC. I hope this helps someone it took me a really long time to find something that actually worked. Don't be cheap and buy the 10 dollar one I don't know if it will work you could always give it a try or get the one that actually does work.
Works as intended. Would buy again.
