Having sent the headset in for warranty repair, it came back and the same issue is present. However, i may be able to shed some light on the wear vs software debate going on. my headset was purchased in march, however it was first opened and used on the 1st of july (as i wasn't allowed to use it until after my exams) and the first thing i did with the headset was install all of the firmware. And have had tracking issues for all of the time i have had it. thus, this suggests that at least in my case it isnt wear as the headset had had this error since the first day of use.
