I don’t remember if we discussed it in this thread, or in the VR news thread perhaps, but I’ve had the online interactive @fearlessfrog encyclopedia explain this to me, at some point…
But yeah, it is an interesting feature. If it works as well as I hope, I guess we’ll see it in more headsets in the future. I think Pimax has an optional eyetracker for their headsets…?
I thought it would extremely adjustable, considering the two straps and tilt function… And I had a very comfortable experience with the halo strap of the Rift S. Unfortunately I think it’s the facial interface that is the problem here. It would probably fit a flatter face better. I have space available at the temples and all the pressure is focused on the cheekbones, below the eyes, and the eyebrows…
I’m looking at ways to modify this.
Speaking of modding…
The sound, or lack thereof, needs attention.
I managed to find my old RiftS headphones, that I modded in this thread and made some adjustments for the Aero. Bad sound in VR headsets is nothing new. No sound, though, in a $2K VR headset…! 
Unfortunately, Varjo seems to hate sound. Is it that they love the peace and tranquility of the deep dark forests, so much…?
There’s no good place to add headphones. I used the old 3D printed rails that I made for the RiftS, added a distance and taped them to the halo strap. It will have to do until I can design new ones.
The sound of these Sennheisers was great for the RiftS, but coming from the Valve designed speakers of the G2, they sound absolutely anemic.
Do I really have to use a complete audio headset, with over ear cups…?
I must see if there are alternatives available.
The way Varjo designed the facial interface means I can’t use the VR cover…cover. I made an internal cover out of neoprene.
Varjo, if you’re listening. This is the kind of stuff you could’ve thrown in with the Aero. Perhaps a nifty little protective bag as well? Would’ve made us users feel better about our investment. Yeah, we’re really that gullible
