My modded Sony HMZ T1. I removed the headphones so I could fit my Senn PC360's and grabbed a hat from work (left over from some indy race sponsorship - thus the checkers). Made one cut where the bill joins the hat, then slid the forehead pad connector through and attached a forehead pad with the pad removed and voila. I don't even use the back straps at all. Fits very well and very comfortable now.
For gaming, it is very nice. The picture is incredibly sharp and feels at least as big as the 110" screen I usually game on from 10'-11' away. The only downside I have with it is that if I move my head while playing, the whole screen moves which is a bit disorienting and has caused me to lose focus and lose a battle. I never realized before how much I moved when playing. Especially when something sudden happens and I jump. Also, if not positioned right, one side or the other can be slightly blurred for one eye. I find I'm very picky about this and always make sure it is in perfect focus across the screen.
Compared to my current gaming rig which consists of a Sharp 12k mkII and a 110" high power screen, it is brighter, sharper and has a much higher contrast ratio. I need to find a good 3D game to try out on it. Might have to buy uncharted on PS3. For movies, I prefer my RS35 though on the 130" wide AT screen.
