The IELTS exam uses different formats for the listening section. You'll have a lecture or sometimes, you'll have a speaker, like a guide, who gives you details or gives you directions about how to get somewhere. Or details about maybe a historical object, or a location. You'll also hear conversations, so you need to practice listening to things that are similar to those kinds of scenarios.
For the lecture-style questions, listening to documentaries, documentary videos or podcasts. Also, TED Talks are really great for IELTS practice. For conversations between two people or among groups for everyday language, it's good to watch TV, watch videos, movies, that's a good listening practice.
