Now, the G35 is actually the most expensive of all, I had expected that this course works great.
My problems with it:
The left speaker is much quieter than the right (estimated 20%), since I'm not the only one, it googling.
Ingame Dolby makes it no fun at all, the spatial sound is indeed there, I can tell you exactly where one stands beside me. But on a few meters distance you can hear nothing at all more. (It's probably just too good in Dolby?).
If you switch the Dolby it goes relatively well, but not as expected, let alone as the predecessor.
In addition, the speakers are very quiet, I turned in Win7 100% and had game further turn up to listen to something.
Now I play again with the Roccat Kave, for me currently the best choice.
