"Listen to you!" and "Listen to yourself!" They're the same? and When do you say it?

Question

"Listen to you!"  and  "Listen to yourself!"  They're the same? and When do you say it?

Answer

Not the same.  Here's how I use them.

"Listen to you!"  
>  "Oh, listen to you!  You're acting so smart / tough!  (But you aren't smart / tough.)"  
To me, it's kind of a sarcastic expression.  You can use it with other adjectives, "smart" and "tough" just came to my mind first.

"Listen to yourself!"
>  "Listen to yourself!  Do you understand what you're saying?"
Usually means I don't agree with what someone is saying, or I think what they are saying just doesn't make sense.

Answer

No, it' not the same. 
First sentence you use when you are angry for someone like: "Listen to you! You never will talk to me like that. You understand!?"

Second senntence you use when someone talking some stupid things: "What are you talking? Listen to yourself! That not have a sense!"
