I bought these headphones about year ago (I use them almost everyday), as an upgrade from my g430s when the cable finally wore out. In some cases (only some cases) I think the sound quality might be a little better on the g430s but being able to get up, walk around, use the headphones away from the computer, in another room, and not having an extra cable to get tangled is so worth the extra $100 or what ever it is you pay for them.
Sound quality is great (you can make them pretty loud too), I take these all over the place just because I can't stand listening to music through ear phones now. Wireless range is a standout, I can basically walk around the whole house without any interruptions, with the microphone or audio.
Also super impressed with the battery life and charging time, I can use them all day without a problem.
I haven't used the microphone in a while, but I remember it being really really good, major step up from the disappointment of the g430 in terms of quality. So quick and easy to mute, easy to re-position.
They have a different feel to the g430s (better fit I think, and nicer material), no problems with it. Before I bought them I read that people had problems with sweaty ears... I live in Australia, it gets pretty hot, but I've had no issues.
Took some trial and error to get them connected to my phone and I ended up having to use a pin to usb adapter (which lucky I already have because apple charges like $40 for) which I then plugged the wireless adapter into (this makes your phone a bit bulky)... perhaps not as convenient as a headphone jack but the wireless works fine and haven't had any problems yet (I guess if you were using them indoors where your phone didn't have to be on you then there would be no problem).
I've never got the software to work, I have a Logitech mouse as well and upon opening the software only the mouse is registered as a connected device, no big deal for me, but I can't really comment on any of the buttons.
The volume wheel is pretty well located though, only problem I have with it is, after unplugging the headphones from the charging cable while in use I have to turn them off and back on again for the wheel to work. Not a huge deal though.
Overall possibly my best value for money purchase ever.
