Gee, I dont know what you guys have actually tried if you don't think they are any good at positioning. Because, I will upload a bunch of kills into my file share where people claim I am a hacker because I am tracking peoples movement within buildings and behind walls and shooting before they come onto my screen and getting the kill. I could never do that with my stereo headset. People reckon I must be able to see them through walls with some sort of hack, but would know if they watched the replay theatre, that its only when people aren't using ninja pro.
In saying that, I do miss my AD700s for the sheer audio gold they produce. the clarity is unsurpassed by any other stereo headset I have heard (That I could afford) and the detail is extraodinary. I just wish someone would develop a speaker driver that was small and could produce that sort of detail into a 5.1 set up.
