Can you simply say "escúchate" to mean "listen to yourself" or does it have to be "escúchate a ti mismo"?

I thought you could use the reflexives like "te" or "se" to indicate doing something to yourself, but when experimenting on a Spanish-learning website, I find plenty of uses of "escúchate a ti mismo" meaning "listen to yourself", but not a single instance of "escúchate" meaning that.

Is there a rule for when you can simply use the reflexive se/te and when you have to add the "mismo" part?
