Only if resistance to significant mechanical stress is required. Which isn't at all necessary for VR headsets, as others use plastic and have no mechanical issues with it.
My father has some plastic camping dinnerware that has been heavily used since the 60's. It's been wildly abused around the world, up mountains, on beaches, by generations of family, kids and bitey babies.
It's not even scratched. I have no idea what it's made out of but it's super impressive. I try not to think about because of whatever the biosafety standards were back then... but the lack of visible damage gives me hope not much of it has been ingested at least.
