Identification of cushioning members in personal audio devices

An earpiece for a personal audio device, the earpiece comprising:

• a housing having a proximal surface;
• a speaker disposed in the housing;
• an attachment structure disposed on the proximal surface and configured to attach to a cushioning member;
• a tag sensor disposed at or near the proximal surface and configured to generate a signal responsive to an identification tag of the cushioning member;
• identification logic coupled to the tag sensor and configured to determine identification data for the cushioning member based on the signal from the tag sensor;
• and
• a controller coupled to the identification logic and configured to receive the identification data from the identification logic.

A method comprising:

• detecting, by an earpiece of a personal audio device, presence of a cushioning member;
• operating, by the earpiece of the personal audio device, reader circuitry to read identification data from an identification tag located on the cushioning member;
• and
• modifying a device behavior based at least in part on the identification data.
