The FreeStyle is the newer version of the MEI2. Other than the color and slightly more durable buttons, they still represent Bose to the fullest. I currently use them with my iPhone 4, my brother uses them with the 5. They are great because you don't have to switch headphones. You can answer/end incoming calls by clicking the middle button and control volume with the top and bottom buttons. The music can be started/stopped by using the middle button also. The music picks up right where you stopped even when the call hangs up. Hope this helps, but I don't think you will be disappointed.
