These mandarin podcasts for native speakers are great for listening practice and they are free. The amount of content on this site is ridiculous.
They have podcasts in most languages. This is all real content for native speakers. Many of the stories are very interesting. And gives you a diverse amount of listening practice as the people are all from different places. These are all designed for native speakers and aren’t rehearsed dialogues.
They also have Cantonese, if your interested in other Chinese dialects.
If I find out how to get the transcripts I’ll post it here, as I know its possible because someone posted some on LingQ a while back.
