The buttons in the headset are actually just levers which tap a spot on the phone's screen. There's something wonderfully low tech about this approach that I really like, and it eliminates the need for batteries in the headset, which keeps things lightweight.
It's not the most comfortable thing to wear, though. The lack of focusing options (there are zero) made it difficult for my aging eyes to focus well on the screen for long periods of time. Most every successful VR headset has focusing options, so this is a sad omission. I was still able to fly without any trouble, but I never wanted to keep it on for too long.
First-Person Problems
I should probably also confess that I have more fun using my drones as flying cameras, rather than racing copters. I understand the appeal of FPV for racing and other scenarios, but it's not my control method of choice. That said, I did have a lot of fun flying the Anafi in Arcade mode, which makes the flight path follow the camera. This felt the most natural way to use the goggle headset. Pan the camera and the drone follows.
The other main flight mode I enjoyed in FPV was Cinematic mode, which locks the camera’s horizon to the drone's horizon. More than anything this felt like an easier version of the old PC flight simulator games I played (or tried to play) as a kid.
There's also a racing preset, which is what anyone with any experience and love of pure drone flying will want to use. I found the responsiveness of the Anafi in this mode to be impressive and on par with DJI's equivalent settings.
The faster, more responsive modes highlight why I don't find FPV all that useful—outside of closely controlled situations. You just cannot see anything happening outside the camera's limited field of view. That's fine for racing on a controlled course, or flying in an area with no obstructions like trees or buildings, but if you're flying at your local park, you can accidentally bank into a tree if you're not careful.
Parrot has wisely defaulted the Anafi to what it calls "film" mode, which gives beginners a nice slow, gentle place to start flying. I'd also like to see Parrot include some object detection and collision avoidance features. These have been standard issue for DJI drones for years now, but the Anafi offers nothing of the sort.
A Bargain?
The Parrot Anafi was not our favorite quadcopter. This new version, with a backpack and first-person headset does cost considerably less than a similar drone and first-person goggle bundle from DJI. The trade-off is, you'll lose a lot of features—including some collision-avoidance features—found in DJI's offering. That may not be a trade-off you're willing to make.
