Check out if there are comprehensible input sites for your target language if you haven’t already, for example fo spanish there is: https://www.dreamingspanish.com/ which puts out videos labeled with various difficulties of speaking and listening

How well does this work?

[mrbombastic]

Pretty well in my experience if you are trying to build listening comprehension and pronunciation. But it is just one tool in tool belt would recommend just as augmenting other language learning tools.

Very well, but it's very slow compared to what you can do if you mix it up with some higher effort activities.
