Valve thought of that. Its got a 1 hour battery life and you have to wait 3-5 hours for it to charge back up!

> For sure not couple of hours in 1 go

Worry not! That's how long the battery lasts!

> How long is that comfortable?

It depends on the person. I can wear my Index on my head for like all day. I'm not sure what my longest Elite: Dangerous session was, but it was quite long. Other people find the same headset to be either too heavy or improperly balanced for wearing more than an hour or so at a time.

As far as motion sickness goes, it has been my experience that you can train yourself out of it. Recommendations:

1) If it doesn't do bad things to you, consume some Dramamine beforehand.

2) Don't play games that launch you through the air or otherwise induce a lot of mismatch between your virtual motion and your physical motion. Seated piloting (car or otherwise) games are one big exception to this recommendation, as most folks have a lot of brain training with "I'm sitting in a vehicle that's moving me around.", so one's brain doesn't freak out so much when presented with those visuals.

3) When you start getting nauseous, stop immediately. If you're still game, come back to play after the nausea is gone, but not before.

Newbies will attempt to power through the nausea, but it's not something you can power through... you'll just make it way worse, which sets back the whole "Convince your stupid brain that the minor mismatches between the visuals and the inner-ear sensations are not the result of poisoning, so it doesn't need to make you puke your toenails off" training that you're doing by easing into this and -if possible- using OTC anti-nausea drugs.

[0] For me, Dramamine is very helpful to prevent motion sickness.

Just used my Vision Pro nonstop on a 9hr flight. It’s a game changer for travel; you disappear into a private movie theater and come out at your destination.

VR enthusiasts will be in VR 7+ hours on a weekend. I regularly clock 4+.

Without a tether to the PC (I have battery in my pocket) it’s pretty okay!
