The manufacturer warranties it automatically for a year. I can't find any place to buy earpieces. When mine breaks, i go in, pick up a new one, open the box, grab the charger and all components to return with my broken one, and keep the new earpieces if I need them. I also buy the best buy warranty, but haven't needed it yet, cuz it hasn't lasted a year yet. They are quick and easy with the return and very nice.
