I've had both the G35 and the G930 (lost my G35 when my puppy got bored and hungry for random cables =\). First things first, I love my G930. For a wireless headset, it is pretty impressive. It's plug and play, so setup is easy, and if you install the software you can customize it (equalizer, voice mod, volume/bass adjustment, etc). Like the G35 it has 3 macro keys, which are the only things I really dont like about it since not many programs support them it seems. Mic has auto mute when flipped up and has good quality when speaking (friends can hear me crystal clear, works great with vent). The sound and bass is very impressive for a wireless set. I'm sure there are audiophile headsets out there that sound better. But for how much flexibility these things have and how good the sound quality is, they are definately a great investment. The battery on them is also VERY impressive. 10 hour battery life, and you can still use them when you have the cable hooked up to charge them. I only use these on late night sessions/playing with friends and have never had the battery die on me (except for once...today...haven't charged it in over a week! lol). Overall, I HIGHLY reccomend these puppies. They truely are worth the money. I use them music/games/VOIP and they all sound great (granted you do need to tune them a little bit to preference). You can also switch between stereo and 7.1 (which sounds very impressive). And on a side note, its nice to still talk to friends/listen to music walking around the house when you need to grab a beer or something. I give these puppies 10/10!
P.S. I've also used Tritton AXPRO, several mid range monitor headsets, and these definately were the best. Only reason why I keep my Tritton's around is because I still play my 360 and ps3 on occasion. And while they sound good, they are not great in comparison to the G930s.
