Modularization of components of an ear-wearable device

A hearing device, comprising:

• a plurality of modules that mate together forming a physical outer shell of the hearing device, wherein:
• a first module from the plurality of modules comprises at least one microphone;
• a second module from the plurality of modules comprises at least one processor;
• a third module from the plurality of modules comprises a behind-the-ear transducer configured to couple the third module to an in-the-ear component of the hearing device, or is configured to communicate with an in-the-ear transducer of the hearing device;
• each module from the plurality of modules includes a respective physical portion that comprises a different, corresponding part of the outer shell;
• each module from the plurality of modules shares a physical interface with at least one other module from the plurality of modules;
• and
• the at least one processor is configured to detect when an existing module from the plurality of modules is replaced with a new module.

A method, comprising:

• identifying, by a processor of a first module from a plurality of modules of an ear-wearable device, each module from the plurality of modules;
• adjusting, by the processor, one or more settings of the ear-wearable device based on characteristics of each of the modules;
• detecting, by the processor, at least one module from the plurality of modules being replaced with a new module;
• and
• automatically adjusting, by the processor, the one or more settings of the ear-wearable device based on characteristics of the new module.
