I have owned all 3 Oculus headsets so far from DK1 to CV1, and the one thing that puts me of all VR headsets is if it's not comfortable. I know a lot of people will say they find CV1 comfortable, but it's obvious a lot of people don't because VR Cover made a PV leather face cover for it. The only reason I kept CV1 was because VR Cover made this PV leather cover it.
The materials other headsets use irritate my face and I just think it makes sense to give use an option to have a PV leather cover. PV leather can just be wiped once you use your headset, but with material it has to be taken off and washed. I'm not that bothered about taken something off to be washed, but I am about comfort. I will have to test Rift -S for comfort when it arrives or see if VR Cover intend making a PV Cover for it.
I know HP Reverb are offering a pro version with PV leather, but all other VR headsets seem to come with that other horrible material. With the PV VR Cover, I can wear my CV1 all day long if I want, but without it I can wear it for 20 mins tops before it starts to irritate my skin. I hope with the new halo design Rift -S will be better for comfort without having to have PV Cover. I have tested a PS -VR headset, but it wasn't for very long. It does seem more comfortable, but I only had it on for 10 mins and can't say for sure what it's going to be like long term.
