Subtitles are a crutch—how do I switch to native content?

I’ve been watching Serbian shows with English subtitles, but I’m realizing I’m just reading the English and ignoring the audio entirely. I want to start listening to local Serbian content without the safety net, but I have no idea how to bridge that gap without getting frustrated. What’s the best way to train my ear to the cadence of the language without constantly relying on translation?
