I’ve been watching short films on youtube (ones I’ve watched so far here, scroll up for ones I haven’t yet) and I feel like this is the best ‘listening workout’ I’ve had in awhile!
The audio quality is often dicey, the short nature means each line of dialogue tends to matter more, and often the type of dialogue seems different than what I hear in TV shows/movies, or perhaps there’s just more diversity in types of speech due to jumping genres every few minutes 
Some, of course, aren’t very good, but a few have been surprisingly delightful. 鏡 and 消えない both had me laughing out loud.
