First a little background.
I'm a gamer and a musician. So I'm always on the look out for gear that performs well in both areas. From the gaming side of things, the most important aspect to me is voice communication for MMO play over programs like Ventrilo and Mumble. At the same time, I do use sound queue's in game to help my awareness and performance. From a musical perspective, I just want good quality. So really, that encompasses the need to have quality in the mic and the ear cup speakers.
After searching around a bit and reading/watching many many reviews of head-sets, it was clear that the Logitech G930's were consistently getting great write-ups. So these are the head set I've gone for and I'm not disappointed at all. The build quality is superb - made from what seems to be a high impact plastic with wonderful comfy cushioning around the ear cup. What also really impresses is the size of the ear cups. My ears sit in them without touching any part of the inner cup, allowing room for the sound rather than having your ear press up against the speaker. Wireless range is adequate at about the stated 40 ft range, perfect for anywhere in my house. The buttons on the head set all have a great feel - almost a rubber texture, with an infinite volume wheel.
Speach quality in both directions is superb being extreamly clear and defined. The mic auto mutes when moved in to its up position which I really like. The mic arm is also flexible for for accurate mouth placement. Last of note is that I am a lager guy with a large head, yet this head-set sits easily and comfortably on the head with the set adjusted to 5 out of a possible 16!
The supplied soft ware has everything you could need, including stuff you don't. There's the rather gimmicky voice modulation which just adds various FX to your voice, and I'm not really sure what this is for. Full EQ control via a software pre-amp. basic EQ controls using high and low filters, and a rather nice piece of software that redirects your voice back to you, to do away with that muffled, talking with your fingers in your ear type sound. Try and you'll see what I mean. Where these head phones come in to their own though, is through the use of the G button control. You can assign media player control to any of the 3 buttons, as well as control VoIP programs if the VoIP program allows for it. You can also download or create your own plugins to further add to the G buttons abilities. I have mine set to control Ventrilo's PPT key by emulating my keyboard PPT key (via a plug-in), as well as controlling iTunes (via defaults).
Sound quality for music isn't what this head-set was made for , yet they do a great job. I will say they aren't as good as the best audiophile phones out there, but they are certainly good enough for pottering around the house without disturbing my wifes TV time. These do require a little burning in time to sound their best, but then, I've yet to hear equipment that doesn't sound better after a little run-in time.
Overall, a great wireless gaming head-set. Highly recommend.
