FPV Goggles (FPV Camera App) is a complete innovative feature that every FPV enthusiast will enjoy flying Phantom 3 and Inspire 1. It turns your iPhone to FPV Goggles with a simple headset (so-called VR glasses, US$10-$50) of your choice. The app converts live video feed to side-by-side format for watching with goggles. This cost effective solution is way better and cheaper than buying DJI HDMI Output Module (US$99) plus a HDMI goggles (US$200-$700).

There is really NO "the best" headset for everybody. You may consider the following factors. • iPhone Size: Headset requires big enough to fit your iPhone. • Aspheric Lens: Due to serious distortion of spherical lens at 4 corners, we suggest to use aspheric lens headset. FPV Goggles is optimized for aspheric lens headset. • Adjustable Focal and Pupil Distance: Different people have different focal and pupil distance in conjunction with different size iPhone. Different people might have different eye problems. Headset is necessary to adjust both focal and pupil distance. • Fit Your Glasses: If you wear glasses, some headsets allow you wearing glasses fitting the headsets. • Heat: Some headsets have closure compartment, and it might cause overheating your iPhone in hot summer. We have tested a bunch of headsets, and found VR BOX (US$20) is a pretty good option for iPhone 6+ and the app. It fulfills most of the aforementioned considerations. • iPhone Size: iPhone 6+ fits well in the tray • Aspheric Lens: Yes • Adjustable Focal and Pupil Distance: Yes • Fit Your Glasses: Depends on the size of your glasses. It marginally fits my glasses. • Heat: Open the camera window helps ventilation to reduce heat.
