Its this product here, the currently popular Zen 2.0
 
 
Im gonna listen through a samsung smartphone, and a fiio E10 DAC. maybe I will get other sources in the future.
 
As I understand, TRRS has 1 more ring than the TRS. What difference does the ring make?
 
What kind of products need the TRRS? If its not a bother, I would like to know, just for information.

You would use TRRS 2.5mm with a balanced source (if i'm reading the product description correctly.) It comes with an adapter, which has some added bulk. Unless you're planning on getting a source that does 2.5mm balanced output like the onkyo dp-x1 it may not be useful.
