Every time you move, your ears flex and change shape. So who ever thought hard-plastic earbuds were a good idea? And those rubber tips do little to keep your ears from aching after wearing them for a while. Buderflys are the only earbuds in the world to use a continually flexing material design that adjusts to your ears as they move and works with your body temperature, making Buderflys more comfortable the longer you wear them.
