This is true, which means that the Clouds and it's derivatives, generally sound at least decent. Not great, but perfectly usable
The mic is still quite poor quality though
Another gamery headset that is actually quite decent would be Cooler Master MH-751 (and 752), which is essentially a Takstar Pro 82 with a mic, but a pretty good one actually. Also it sounds clearer than the 80.
That being said, gaming headsets' prime selling point isn't actually sound quality or performance in games (which is quite ironic), it's the convenience of not needing a separate microphone.
Most gaming headsets are perfectly usable for gaming, even competitive gaming, but most aren't very good at it, few are great and fewer still are great AND comfortable.
