My experience has been that listening is basically a way to learn the language with a minimum of effort. Context and non-verbal communication often make it clear what many unknown words in a sentence mean, making it not only possible to understand speech far above one's vocabulary level, but to actually to increase one's vocabulary through listening. These non-verbal cues and context are mostly absent in written texts.
Your method also seems counter intuitive as children learn languages primarily through listening, as they are for the most part illiterate.
"Children" take almost 20 years to learn English at high proficiency.
And the context stuff doesn't work for me in audio, not until years into a language. It might be easier with a language close to my native, but otherwise...
