I have been searching for months now, for a functioning 20'+ USB 3.0 extension cable, I have tried several, to replace four aging cables that have recently seeing spotting connectivity. I actually have four, as I am typing this, that I need to return to Amazon, as Windows 10 refused them, seeing them as "Ultra High Speed USB Hub", but my Windows Device Manager would refresh, constantly, when any of those four cables were plugged in. Those cables were even more expensive than the BlueRigger cables.Not only have all of those issues gone away, as soon as I plugged in this new BlueRigger cable, they function perfectly, including plugged into my Fiio Q7 DAC. Every other extension cable I have used with this DAC, even others that indeed worked otherwise, there would be an occasional crackling sound, there are no such artifacts with this cable, my audio is crystal clear. You can feel the quality of this BlueRigger cable, when you are holding it in your hand, and everything works just as well as if it were plugged directly into my PC.I cannot recommend these BlueRigger cables enough, and they will be the only cable I buy, moving forward, certainly on the extension side of things, but once I have tested some of their standard cables, they may be the only cable I ever buy, moving forward, for any sort of connectivity I may need. As a matter of fact, I only ordered 2, due to all of the issues I have had to this point with other cables, and as soon as I finish this review I will be ordering two more. If you need a USB extension cable, BUY THESE BLUERIGGER CABLES!
