I really like the G733, it's the only over-ear headset that doesn't give me a headache as I wear glasses. The only problem I have is that in meetings the microphone seems to go into a kind of standby after 30 minutes. So even if I'm actively speaking, after about 30 minutes I can hardly be heard, or not at all. GHUB is installed. I can't find anything about it on the net. Does anyone else have this?
