Horror games and movies it’s PERFECT for. Music is the only time it REALLY falters. Some games are all messed up when it’s on, but for horror stuff it’s perfect.
My podcast program I use, Overcast, has something called Voice Boost. It does the same thing and it makes podcasts listenable with my car’s crazy sound system and sub (I am not shilling, I haven’t paid for it and I should but I never buy phone programs… even though I probably should I know I suck)
