Movies sound like you’re in the cinema with the SXFI mode on. No joke.
I watched Spider-Man: Homecoming and John Wick. Conversations sounds like you’re in the cinema, again because the vocals aren’t firing right in your ear. Especially that fight scene in John Wick in the bar fighting, with SXFI the background music was nicely weaved into the background amidst the gun shots and action, instead of being blaring loud when SXFI was off. It just feels that the overall sounds in the movie are better distributed and more well-balanced.
If you do watch a lot of movies or TV shows, the SXFI sound is really a game changer when it comes to the experience.
