Ah, gotcha! I’ll give you what info I can!
The dongle does have options similar to those in your linked images. I can’t test if it has any impact on the hiss right now as I’m working remotely on a laptop, but my gut instinct is that it won’t since the hiss seemed directly related to the impedance/sensitivity of the headphones I used, and using the hardware mic mute button on the dongle has no effect on the hiss.
There’s not much difference in surround quality between the Revolver S and the DT770 out of the dongle…but that’s more a testament to the quality of the Revolver S. They’re pretty darn good headphones, and they measure far above their cost.
I don’t know that the Revolver S Dongle offers you too much more portability beyond the older Logitech dongle. Yes, it does work driverlessly with USB ports…but it’s still at its best hooked up to a Windows PC. There, it shows up as a full 7.1 device. On my PS4, it only gets stereo. The surround effect is also not adjustable. You’re stuck with HyperX’s customized Dolby Surround profile. You can’t pick from the different Dolby Headphone room types, for instance, which I believe the old Logitech dongles let you do.
As an upgrade to the original Revolver, the S is a great value. But if you evaluate the dongle on its own…at this point you’re probably better off with a nice portable headphone amp and the new Windows Sonic/Dolby Atmos software, if you’re on Windows 10 and looking to make a change. Heck, if you’ve still got the E5 lying around, that’d work too. I guess I don’t have a full picture of what your use case/use environment is.
If you’re on an older version of Windows, then I don’t think the Revolver S dongle is going to do too much for you the Logitech one doesn’t already do. And for less than the $150 the Revolver S goes for, you could pick from several good portable amps. I use a Schiit Fulla as my main portable solution…and although it’s stereo only, on a Windows machine I can use Razer Surround or Windows Sonic or Dolby Atmos to push virutal surround through it if I need to.
The Revolver S is really designed as a package. It’s not meant for crazy people like me to plug DT770s into, haha. I just found it to be a nice bonus.
Hope that helps you out in some way! Thanks again for reading and replying!
