I think they all claim to block the red and white flash, but there are wide variances as to the actual performance of the glasses.
The ZD201's are ~$100 and are the first pick to match with the W7000. The less expensive True Depth 3D's are the 2nd pick due to comfort (large lenses for prescription glasses) and very good ability to block the red flash.
These are the ZD201's next to the new BQ glasses
The glasses in the back, left side is the True Depth 3D's.
