I decided to purchase a pair of these because the pick-up on my 3.5 jacks is low on my ASUS motherboard and I had seen this headset worn in a Twitch stream by Bioware employees where it appeared to have a good mic sound. I needed a relatively decent USB headset and the ratings on this one were generally good.
I ran into several issues. The drivers from Logitech failed to properly download for Windows 10, until I found them elsewhere on the Logitech site ( the file they had loaded on the headset page itself, for Windows 10 64-bit, was the wrong file.) The headset itself is cheap and overpriced for what it is, and it shows, and feels it. Light plastic with hard "cloth" plastic mesh ear cups that for some reason are square instead of round, and block out almost no external noise, and I did not find them particularly comfortable.
At first, the microphone sounded awful, skipping in and out, requiring I download a firmware update from Logitech, and then update the driver software, which involved plugging and unplugging the USB multiple times, and configuring Windows 10 sound options. (Sidebar - If anyone with a Realtek driver is reading this, I advise removing the Realtek drivers and using the default WIndows 10 sound options, then whatever software you want - in this case Logitech.) You will also need to disable to microphone output through the headset options unless you want to hear every breath you take. While this is a good option for those doing voiceover while playing, the white noise it produces is excessive.
With software and firmware both up to date, and without other drivers (Realtek) interfering, I was finally able to achieve good mic and decent sound. However, the constant creaking of the cheap plastic headset and the rubbing of the cloth cord against any surface was so loud and disruptive that I couldn't continue to use them. Further, the USB produced uneven sound between left and right ears, causing me to go into Windows and adjust the balance, there. I can't speak to the 7.1 Dolby Surround emulator because I dislike the echo-effect it produces and prefer to leave such things up to the game software itself, so I did not use it.
If you are a casual gamer unconcerned with things like white noise static, uncomfortable ear cups, cheap build materials, and problematic software, but you have to have a blue and black headset, this could be for you.
Instead, I would recommend the Kingston HyperX Cloud, which is a far superior headset (in both USB and Analog varieties) for slightly more money.
