The DasGut GX-30 glasses in vertical extent a bit narrower. The Blue Heaven DLP Pro 4G is in vertical extent not very wide, but it is something more than the DasGut. For those who appreciate more "expansion" in the vertical, which was the Blue Heaven prefer. Really needed the greater expansion in the vertical direction is not, however. Even very close (1.5 m) in front of the projection ranges from the "vertical dimension" of DasGut to view the image in the entire vertical extent can.
Both glasses are switched on when pressing the power key for one second (one flash a green LED), when operated for three seconds glasses is, however, switched off (three flashes a green LED). When DLP Pro 4G to power button and LED and the microUSB slot for charging are in the middle of the glasses up, there the eyeglass bridge is almost straight and the Micro-USB connector can be infected well. When DasGut GX-30 is power button and LED are on the top right side and the microUSB slot on the bottom right side (a little before the "retirement" of the right eyeglass temple), there of course the glasses surface is a bit sloping. When inserting the Micro-USB connector of this thus puts on one side entirely in the slot on the other side there is a small distance from the surface beveled glasses. I fear, with frequent or careless use could occur at this point to a loose connection. To avoid this, I plug the USB charging cable an increasingly cautious.
Another minor difference is in the synchronization. When I go out of the room and look into bright light so that the respective glasses desynchronized, and then come back into the living room, it can in two glasses happen that the glasses confuses the right and left signal, creating a peculiar 3D impression (everything should protrude what "out of the picture", is now "inside" and vice versa). The DLP Pro 4G glasses synchronized in 3-4 seconds by itself, that is, right and left signal be recognized properly, and the 3D effect is again correct. When DasGut it may happen that the glasses confused the left and right signal for a long time and is not automatically synchronized. To solve this problem there is when DasGut a very good solution: If you tap the power button on the top right with active glasses very briefly, right and left image are reversed. in effect, one can in this way a possible left / right to correct reversed within one second, by tapping the power button briefly. When Blue Heaven there is this functionality not mean you have therefore always wait for the few seconds it detects the Blue Heaven left / right then automatically correct. Basically you can say that this problem is not very relevant, since one usually sees a movie anyway completely. And if you leave the room and come back again, it is my opinion not a tragedy if the image after you have lightly the power key (DasGut) or after a few seconds of self (Blue Heaven) is correct again.
It should be noted would be that sold with the DLP Pro 4G lateral "mirror protection" stickers are in my opinion pointless, firstly unnecessary and secondly see this expresses "cheap" from: One would have this "mirror protection" from a pre-perforated self-adhesive plastic film cut. Then I have omitted, I think with these stickers would the "Blue Heaven" glasses pronounced "cheap" look.
From the comfort both glasses are lightweight, extremely pleasant but not good to wear both on a long time, in both cases you have a certain "plastic feeling". Personally, I felt more comfortable the Blue Heaven from comfort than one track.
Then all that remains is the price, which is significantly higher than for the DasGut GX-30 for the Blue Heaven DLP Pro 4G. Whether the small differences are worth the Preisunerschied, everyone must decide for themselves. Incidentally, I have to keep both glasses.
