After seeing two people recommend the G430 I have to jump in and say avoid these like the plague. I used to have a G35 until the microphone broke and the leather perished, but now I sincerely regret buying another Logitech pair. I totally forgot how their drivers and Game Centre software is completely broken. There's a significant bug with their drivers which makes one ear louder than the other, due to the fake software 7.1 they use confusing Windows. It took me months of tweaking to fix it with the G35s and then it was back with the G430s as soon as I started using them, and I can't replicate the fix.
The software EQ used to be the only saving grace of the headset too, as by default they are way too quiet. You used to be able to crank all the dials up to get a reasonable volume from them, but a software update a couple of years ago made it so that turning up one range on the EQ turns down everything else an equal amount, so no more audio boost.
If you are planning on using the microphone, don't bother. It has really bad software noise gate that is so slow to activate that the first syllable of each sentence you say is not recorded, because it will still have muted your mic. The software issues are so bad at this point I'm forced to just use the headset plugged in via the 3.5mm jack to avoid it.
Just buy a nice pair of Sennheisers or actual headphones (which it seems like you're planning to do) - I know for sure I'm never touching a gaming headset again.
Huh. Weird. I have none of these issues. I use the headset for work as well (remote tech support by phone) and I don't recognize the noise gate issue. Ah well, guess it's good for OP to know it doesn't have a spotless track record. If it was just a software issue it might've been fixed by now.
