Just a brief review to those of you looking for budget 3D glasses.
There are two active shutter versions offered by SainSonic: IR and DLP-Link. Both will function fine with DLP TVs. However, as discussed in previous posts, the DLP-Link type are preferred to achieve non color tainted deep blacks.
-CHEAP (can be found for $40 shipped)
-Built in rechargable Li-Ion battery (fully charges in under 3 hrs, good for approx 50 hrs between charges).
-Excellent syncing. Quick sync-up. No problems whatsoever even at 30 feet away from screen in a _very bright_ daylit room! I was extremely impressed there.
-I didn't detect any flicker or notice any rainbows during bright scenes. Their polarization seems to be a perfect match for the HL61A750's optics.
-Very minimal ghosting at max 3D depth settings. Slightly better than the Mitsu glasses in that regard.
-They look more stylish than most other brands and they fit well over large presciption glasses. Not heavy or bulky..feel great to me even after extended use.
-Seem slightly dimmer than the Mitsu IR glasses.
-Contrast and colors are _just a hair_ less glorious compared to the Mitsu glasses. I am very picky though. Detail is still top notch.
-A tad bit of internal light reflection at the peripheral (nothing major, most 3D glasses have this problem anyway).
-Must set 3D TV selection to Mode 2 for these. Unfortunately my pair of Mitsu IRs are optimal with 3D Mode 1.
-The charge cable is not a standard USB miniport connector. Do not attempt to jam a miniport plug into the charge port. Must use the supplied charge cable.
Summing it up:
I'm happy with them and would not hesitate to grab another pair. Sure there are better solutions out there, but they really aren't -that- much better enough to justify their price.
Sure.....still want a pair of ZD201s, but until then, these are more than adequate and will continue to get plenty of use.
