I have just bought a pair for my MA2 actually. I have been told that you can use the goggles with use of a chromecast.
I have yet to see how great this is.. untill now i have used Maven app (iOS) and a pair of Zeiss VR goggles. It has been great and you can head Track the gimbal as well. So honestly i Think Its a set back with the DJI goggles, but the were cheap and i can sell them again if the Maven/VR setup works better.
I can let you know the outcome once i have tried both setups.
