If spending the the 20 dollars extra for the RED just means eating bean salads instead of McDonalds burgers for a wee or two, then it might be worth it. For movies, it would give you more distinct sub-bass.
For gaming, you might want to consider the 7hz Salnotes Zero instead of the Wan'er. The Salnotes Zero has a touch less bass, but a little bit more energy in the upper mid range and treble, which could make it easier to hear footsteps and other details in games.
