The accessories kit is really the only "mandatory" thing on this list due to the hand straps for the controllers. The top strap for the headset seems to be personal taste with some people hating it and some people needing it.
Charger + cable - $30
Most people already have chargers and cables for this, even for 45W.
Please note that, for some reason, there is no 3.5mm jack
This has been a thing with smartphones and motherboards for years. This is too old to actually ve an argument anymore. If someone wants to use 3mm jack they most likely already have a splitter
Headstrap + headphones and battery - announced, no price yet
That's not really even announced yet. It's an "fyi we're wanting to drop this in a few months" they told reviewers
Quite being pedantic just because you got called out for being wrong.
