Not sure if it's different from the 2008, but on mine there's a button on one side, and on the opposite side there's a small hole. Take a wire coat hanger or small Allen wrench and push it into the hole while pressing the button. Pop the headrest off and flip it around, or toss the headrests in the trunk like I did. :)
You need to use a coat hanger or thin piece of metal to keep the seat locking tab from catching the headrest shaft. picture http://www.ponyperformance.com/tech11.html
There is no way to remove it.
