I am a bit undecided about the 3D-sound effects and did not try it yet. Is it really of value or is is a distraction feature? This surround feature reads nice, but unless I have an AHRS in my headset the spatial distribution will stay no matter which direction I turn my head, or? So, if Co is on my right ear and talks to me, I turn my head to look and speak to him, he still will be right, not front? If I turn back to see Pax, their Audio will still be "behind" me? Sounds weird to me. For Monitor mode with TWR and ATIS I am almost fine (although I prefer to listen to only one speaking), but the rest?
