1. A method of designing an earpiece for a user, the method comprising:
electronically obtaining 3D scan data of an ear;
electronically generating a model earpiece with an earpiece configuration based on the 3D scan data;
after the model earpiece is generated, electronically evaluating the model earpiece by a processing unit to determine whether the model earpiece is too protruding, too tight, or too loose for the user before an initial physical earpiece is provided to the user, wherein the processing unit is configured to perform a comparison between a misfit parameter for the model earpiece and reference misfit parameter for reference earpieces;
electronically determining, by the processing unit, information regarding a personalized earpiece based on the model earpiece and the misfit parameter; and
providing the information regarding the personalized earpiece for processing by a manufacturing entity, wherein the manufacturing entity is configured to produce the earpiece having a physical feature corresponding with the information regarding the personalized earpiece.
