I finally had some time to go to a Sony Store at Umeda to test this display.
There were no lines and the clerk was happy to help so I stayed a while.
I did not read most of this thread so probably I will repeat stuff already in here.
Headband behind the head is indeed a bit uncomfortable as I felt it was always too high and fitting the set on my nose seemed awkward. I did not notice to ask if the nose piece can be changed. Hopefully it can.
Earpieces are round, cheap looking pads that slide about 5 cm from their place back and forward and tilt a bit up and down for placement. The clerk told me that they cannot be removed, and it indeed looked like it. The wires run inside the frame so it's going to be difficult. Using a bluetooth mic with this seems like a problem too.
The basic distance between your eyes is adjusted with two slider between the set using a welcome screen text, after that the viewing can begin.
First I got to see the only demo they had of the new Spiderman reboot. Was nice to watch and you feel a bit of vertigo when he jumps the building.
However, I don't think the screen size felt that big for me. If I can guestimate, I'd say about 60-70 inch screen and this is totally out of my ass numbers. I thought it would be bigger but it was still nice but I wanted more.
Colours pop out well and the screen looks good. I could tell that it is not full HD but not even close to SD either. Good enough but what can you expect from tiny OLEDs.
What I liked most was that there was no crosstalk so 3D felt like it should be.
I also asked if I could test with a PS3 and after complaining that there is currently no sound from the PS3, and me saying "it's fine", he booted Gran Turismo 5.
I've never played this in 3D so all I can say that it was easier to estimate distances and corners, but the game itself was less pop-out 3D than the Spiderman trailer version. It did run well though even with 3d on. The replay of the cars on the other hand felt a lot more "popping out of the screen" and those clips looked really nice.
Even though they are only 420 grams, I think 400 grams out of those is in the front. You definitely need a back leaning chair for this.
Another problem was that the Sony Store was full of lights, so when I asked for the blocks to block out the light, they really did nothing as they are fitted only under the device, not on top at all. I tried holding my hands on top of the device a bit for better performance which helped slightly.
I suggested that they let people try this in a darker room in a chair. This way I think the best experience can be had, and a sale can be done easily.
I was really hyped when I heard the announcement earlier this year, but when I tried them, I'm now a bit confused even with the excellent 3D effect. With the japanese price being so low compared to EU, I still think I will wait for next version, or test in a better environment first with more time and more questions.
(As a comparison, I tried 3D tv's at Yodobashi camera too just for fun as I bought a smaller Sharp TV for home today. The Sony LCD's seemed nice and Motorstorm looked fabulous! But the bigger the screen was ,the more flickering I got. OR the batteries of the glasses were low or something. Crosstalk here and there but not that much.
LG, (the passive ones touted by a guy here a lot), were actually really nice and light. The effect was clear and had only a bit of crosstalk when some FPS demo's weapons came out of the screen too much. I could not tell if the resolution was halved like some point out. It was good enough for me. Tilting my head to the side, and the picture went weird. Do not like that feature, but it's a passive glasses con that everyone knows.)
