Did a ton of research on the different dji headsets. I pretty much just started to ignore dji stuff a few years ago since I was only flying analog so I'm rather out of touch. So far i'm fairly sure i've settled on the DJI n3 instead of the goggles 3 or integra. A fair bit cheaper ($220 vs $400) and from the reviews i've seen a bit better for glasses wearers (of which i definetly am one) since there is a bit of extra space in the goggles. Annoyingly the o4 pro unit seems to be very much out of stock pretty much everywhere. I've stuck out some feelers on ebay and a few other places to see if I can get one used for around the same price or just a tad bit more than new.

Just made the wiring digram! I did it on figma over at [https://www.figma.com/board/V3yHTGLW7VbZYWka2fCPID/tern-wiring-diagram](https://www.figma.com/board/V3yHTGLW7VbZYWka2fCPID/tern-wiring-diagram?node-id=0-1&t=AxakkIcfGteMs2AB-1) and it wasnt terrible! I would have prefered slightly better routing but idk you do what you have to :)
