Two things
1) I don't know if anyone has noticed it or agrees. BuO or maybe it depends on the game, some presets just lend themselves a lot better to sound localization.
Like for example i was playing a game on the "music" preset (first time) and the sound was very pleasing but the localization and imaging was not as clear as it once was with RPG , Default or Ballistics.
I don't know if its just me getting used to the different sound but doing several tests I thought the differents were pretty consistent.
2) There's a new device by Creative coming out, will retail for 150usd. Its basically a poor man's version of the Realizer but apparently its REALLY good. It was at CES this year and people were really amazed by how good it was. It uses HRTF and will launch soon in Singapore. Creative has special hardware to do measurements for HRTF but they will also release a phone app to take pictures of your head and ear that is "80 percent as good" as the real thing.
I think it's called Super X fi

Im looking forward to the super x fi but it's 3.5mm out only
Which would make the headtracking impossible with the mobius .
