...for the record i jumped from Q2 to Q3 pretty much on launch, and saw a definite improvement then, and it's only gotten better since.
One of the endearing experiences of the Q2 was how much it changed over the years. The constant software upgrades meant it was a far better machine by the time i retired it, and i'm seeing the same ethos applied to the Q3. These headsets are far more of a work in progress than the average mobile phone, to be sure. And they're pretty resilient... and lube proof... which is nice...xD
