Adjusting your sound settings is the first thing you should do to better hear enemy movements in Fortnite. Make sure your headphones are adjusted, and change the sound settings in the game to make footsteps stand out more. Maybe it will help if you turn up the sound effects and turn down the music.
Next, you might want to use a high-quality headset, which can make it much easier to pick up on quiet sounds like footsteps. Also, make sure that your audio drivers are up to date. Drivers that are too old can cause sound problems.
The last thing you should do is use the Epic Games launcher to verify the game's integrity and fix any broken files if you're playing on PC. Make sure that Fortnite is fully updated, and try out different in-game settings or different audio sources to see if that makes the sound better.
These are key methods that we can offer. If you have more, please share.
