Struggling to parse the 'en/ei/et' gender of nouns when listening to dialects

I’ve got the basics of Bokmål down with gendered nouns, but as soon as I listen to someone from Bergen or Stavanger, I completely lose track of which gender they are using because the endings get swallowed. How do you all handle the gender variation across different Norwegian dialects when your ear is only used to standardized textbook audio?
