I had my HP Reverb G2 suddenly develop blackouts after 10 minutes or so, this after nearly a year of working perfectly. I contacted HP support, they supplied a replacement cable assembly, which sadly failed to cure the issue. HP phoned me to check whether I was now ok, and having got my progress report they have now shipped a replacement headset, which has yet to arrive, the cable actually came from the Netherlands to the UK, I guess the headset will take the same route. Anyway, I also can report HP support have been excellent.
