Until quite recently I've had a G35 which I was really happy with. Unfortunately the cord got stuck around my chair and as I tried to stand up (unaware of the problem), it got yanked off of my head an the left earpiece broke off. I tried to fix it but ultimately had to give up.
After that I decided to try the G930, hoping to avoid the cord problems in the future. So far, I am very much content with my purchase, it pretty much offers all of the features of my G35 but it lets me wander around most of the house with my music still playing. It's expensive but if you have the funds, the G930 is totally worth it in my opinion. Then again, all of my PC accessoires are from Logitech so I might be a tad biased.
