Plateaued at 'Intermediate': Moving from subtitles to native content

I've been learning Arabic for two years and can handle basic news reports, but I hit a wall as soon as I switch to native content like Gulf podcasts or Syrian dramas. The emphatic consonants (ص، ض، ط، ظ) sound indistinguishable to me when they speak at natural speed. Does anyone have tips for 'active listening' exercises that help me break through this barrier without getting discouraged?
