ChineseForUs offers a large number of free videos on YouTube. The most basic lessons are much like other lessons found on YouTube, but if you skip to HSK 2 or so, there’s a surprising amount of Chinese-only content which is great for listening practice. You can ignore that it says “intermediate” on these lessons, because it’s still very much on a beginner level.
Pros: Clearly spoken, mostly in Chinese
Cons: Only available on YouTube
Sample video: Listening Practice I.I
