Thanks for your question!
It's safe to say that most of us understand how it feels to want the exact model of sunglasses
you came across. Unfortunately, after an excessive amount of time on the web to see what they were, I came up with no results. I see why the suggestions for the Super People model was thrown out there as a possible match, but I agree that they are not the same. The one Taeyang is wearing in the video has the temple arm almost overlapping the lenses and the Super People model does not. I am sorry we could not have been of more help, but it seems to be a very unique model.
We hope you find the exact model for them.
Please keep us posted!
