Got my Samsung Odyssey today and spent the last couple of hours messing around with a few bits to see how it fares...and it's a thumbs up from me. Like the other WMR headsets it's proper plug n play stuff here, took 5 minutes to set up out of the box. The headset itself is incredibly comfortable, moreso than any of the others I've had. The padding and earphones combined are a great combination and it sits in place nicely when tighten accordingly.
The physical lens adjustment is the first thing that sets this apart from the other WMR headsets and it got rid of the issues I had with the Lenova HMD.
Putting the headset on and the screen pops into view with almost crystal clarity (compared to other headsets) and the uptick in resolution was obvious in everything I looked at. Thinking about it now I don't even remember seeing any God rays. I will check again tomorrow.
The only slight downsides for me:-
The controllers are pretty good but they are not as ergonomic as the Touch controllers and of course some games you have to try and work out how the controls work as the WMR controllers don't have physical A/B buttons etc, most are just replaced by the track pad (which isn't really an actual trackpad). This will become natural with more use. I played Brass Tactics, Space Pirate and Robo Recall for a while, as well as an hour in Google Earth, and had not issues with the controllers and never had a proplem with tracking etc.
Other slight downside is heat. As a result of the padded leather (faux leather) design it gets quite hot in there. The new design makes it nice and easy to wipe clean but I will be looking at options to get some air in or perhaps just set up a small fan for when I'm playing. I shouldn't complain really because the headset is so comfortable and inside it's pitch black with no light finding it's way in.
So I can happily say I am very happy. So far it cost £493 including shipping, but I am excepting a bill from Fedex for vat/duty.
I am really looking forward to taking it on the patio next week when I have a week off. Inside out tracking has worked just fine for me with this and the Lenovo so that's a big plus IMO, I wont need cameras/sensors in the front room and the Rift can live attached to my racing rig. Saying that, I will be giving the Odyssey a few laps on my race stuff this week and maybe I'll end up with one HMD to rule them all
