How should I practice 聴解?

My goal (for now) is to pass JLPT N4, but I can't do that if I can't understand the things I'm listening to. Does anyone know any resources I can use or how I can improve my listening skills? I don't have any friends to help me with listening atm, so unfortunately that's not an option. I've been doing immersion, but that doesn't seem to help much since most of the time I'm just watching the screen and getting a general idea of what's happening.
