Earbuds are a promotional cosmetic item for all classes. They are a stylized version of the white earbuds that normally come with various handheld Apple products. They are connected to the class via loose cords. When worn, white musical notes are intermittently seen playing from them. The musical notes have no associated sound effect.
This item was awarded to players who launched Team Fortress 2 using the macOS operating system (at the time Mac OS X) between June 10, 2010, and June 14, 2010. The offer was later extended to August 16 before coming to an end.
