Negatives:
The 7.1 driver the Logitech Gaming Software is a Software-wreck full of crashes and unreliable
permanent, albeit slight high-frequency whistling in the ears when the machine is turned on
The headset has only 2 channels, no physical 7.1
surround impression is modulated in software, what the resources (CPU and RAM) is
"Plastic Bomber", the device looks very unwertig in hand, rattles and creaks with every slightest movement
Soft Touch case each finger burns itself formally into the surface
and is difficult to clean, also
is to be expected that the thin siliconing detaches with time
Headband and ear pads are covered with thin synthetic leather that is flaking off in the shortest time
The USB transmitter the size of a lighter that is nowadays actually small (see Logitech H800)
The soldering of the USB port are poorly processed and tend to a few months of use to break
Actually, the G930 is a very great headphones, the sound is truly remarkable for a headset with its own USB sound card and is only slightly behind my wired Sennheiser G4ME Zero, against whom he had to be measured.
Unfortunately, the creaking of the G930 was simply unbearable and EIA 179 EUR also intolerable. Had it been in my hand still matter, these noises occur even at very low head movements and are so loud that they even bothered my environment. From "immersion" in the game unfortunately so there was no question. Really annoying. In 7.1 mode, the Logitech Gaming Software crashed regularly and only a reboot let me hear sound from Windows again. Fortunately, the 7.1 function purely marketing thing, because it is only a 2-channel headset. In stereo, the device operates just as well without driver and virtualizing 3D sound I prefer to leave the games themselves, if they support it.
Together with the high-frequency whistling, that one has in quiet passages on the ears and the many "breaking points" (Soft Touch case, earpads, USB port), were with the too many compromises.
The unit returned to intensive testing after even a replacement-unit brought no improvement and even worse whistled as the first. Schade Logitech ... a real shame that a principle so great device is sold in such inferior quality for years.
