Factors like weight and comfort often arise. Perhaps a future strategy in this space will be to minimise the headset componentry by shifting as much as possible externally, similar to how Apple has approached the battery issue with the Vision Pro.
(imagination running with that idea : future iphones and Macs will be the processing units for more-compact future Vision Pros)
This whole approach is an evolutionary dead end. If users have to strap anything to press against their faces all around their eyes, forehead and cheeks, adoption's going to be limited to a small group of male gamers, think 10 million MAU in 5-10 years ("Quest" got 6M in 10 years) not 100 million and certainly not a billion. This product is a flop that should have stayed in R&D for 10 to 20 more years until the tech was ready to build something that didn't make your face look silly.
Jobs would never have released this. This is the DynaTAK, not even the StarTAK, and certainly not the iPhone 1. Apple didn't rush to build a mobile phone in the late '90s when the StarTAK was showing that cell phones could fit in your shirt pocket and work pretty well. They waited another decade until they could build something truly good, not just good enough like the StarTAK. But Tim Cook shipped this DynaTAK+ headset that dorks your face.
That's just the kind of good solid work a fashion tech brand like Apple needs /s
