I love my G930. Ive had two of them. The first broke after 6 months or so(my fault i dropped and mic broke off).ogitech replaced it for free. Anyways the sound is wonderful with surround turned on, i havent noticed weak bass. Music sounds great, so do games. Only problem is once in a while the wireless will get interfered with and it takes like 5 seconds to sync back up. Happens maybe 3 times a week and i have to ask my vent buddies to repeat what they said. But its not a big deal. Battery life is fabulous and it can be plugged in and used at the same time
Have had my G930's for 2 weeks now and they are pretty good. Not as good as my Corsair HS1's were, but they have the added convenience of being wireless so I am satisfied. I find the Bass to be decent, it does bottom out on the rare occasion though, like when a Reaper ship in ME3 does it's horn blast thingy.
Another area they can be improved on is the structural stiffness. They are quite flimsy and I find myself having to adjust how they sit on my head a lot because it affects the audio. They are quite light and comfortable though.
Yet another issue is that when my system restarts, I need to unplug/replug my wireless dongle in order for the Logitech Software to find the Device. It sits in front of me though, so it's not too inconvenient. This might be a Windows or even Motherboard Hardware issue with my system though, after the most latest Windows Update I have been having other issues as well, such as Gadgets shutting down and some Startup Apps running, but not showing up in the System Tray. Anyway, I'm straying off on a tangent.
All in all, really good Audio with the convenience of being wireless. Would buy again.
