No need to be sorry my friend. To tell you the truth, sound quality wise It is hard for me to state a preference between my X3 and my X5. I use them both quite a bit and really enjoy them both. I like the X3 for it's smaller size and how easy it fits in a pocket. I like the X5 for the extra capacity. I guess if forced to choose I have a slight preference for the sound of the X5. They are both very, very good and when I am using one I am not missing the other. Unless you want to carry 256 GB of music with you, the X3 is a good choice.
