I only mentioned that I use open potable earbuds. As i have a preference for that over closed headphones.
The reason I am interested in mobius is the head tracking and it's wireless-ness. I have always naturally turned my head in games to hear something.
These days I try to get more wireless gear as it gets better and better. Look my Logitech G603 mouse has lasted me 10 months on the same batteries AND it is not only cheaper than most wired mice, it also matches if not beats them in performance.
I currently have HD660 S running off my HA-1, so it's not like my setup is not capable. Still can't get my speaker sound trough, That is why speakers still take priority. So I don't mind losing a wire or two, Because I tend to use headphones only when needed, but always in games.
